Abstract:

The basic notion underlying urban underground development is that underground space is a non-renewable resource, therefore planning its use must be done in a sustainable, environmentally-responsible manner with due account taken of economic, functional, social, and legal aspects. This paper addresses issues related to the planning, siting, design, construction, operation and maintenance of underground structures in the city of Moscow. The mechanism of the interaction between an underground structure and the surrounding rock masses is described. It is shown that underground engineering can be significantly enhanced through the use of expert systems. The paper also discusses the need for changes to the legal framework for the use of urban underground space.

Abstract:

Presently, we developed a novel robust motion estimation method for localization and mapping in underground infrastructure using a pre-calibrated rigid stereo camera rig. Localization and mapping in underground infrastructure is important to safety. Yet it’s also nontrivial since most underground infrastructures have poor lighting condition and featureless structure. Overcoming these difficulties, we discovered that parallel system is more efficient than the EKF-based SLAM approach since parallel system divides motion estimation and 3D mapping tasks into separate threads, eliminating data-association problem which is quite an issue in SLAM. Moreover, the motion estimation thread takes the advantage of state-of-art robust visual odometry algorithm which is highly functional under low illumination and provides accurate pose information. We designed and built an unmanned vehicle and used the vehicle to collect a dataset in an underground garage. The parallel system was evaluated by the actual dataset. Motion estimation results indicated a relative position error of 0.3%, and 3D mapping results showed a mean position error of 13cm. Off-line process reduced position error to 2cm. Performance evaluation by actual dataset showed that our system is capable of robust motion estimation and accurate 3D mapping in poor illumination and featureless underground environment.

Abstract:

Remote sensing images find application in several different domains, such as land cover or land usage observation, environmental monitoring, and urbanization. This latter field has recently witnessed an interesting development with the use of remote sensing for infrastructural monitoring. In this work, we present an analysis of Sentinel-1 images, which were used to monitor the Italian provinces of Bologna and Modena located at the Emilia Region Apennines foothill. The goal of this study was the development of a machine learning-based detection system to monitor the deterioration of public aqueduct infrastructures based on Persistent Scatterer Interferometry (PSI). We evaluated the land deformation over a temporal range of five years; these series feed a k-means clustering algorithm to separate the pixels of the region according to different deformation patterns. Furthermore, we defined the critical areas as those areas where different patterns collided or overlapped. The proposed approach provides an informative tool for the structural health monitoring of underground infrastructures.

Abstract:

With the pressure of the increasing density of urban areas, some public infrastructures are moving to the underground to free up space above, such as utility lines, rail lines and roads. In the big data era, the three-dimensional (3D) data can be beneficial to understand the complex urban area. Comparing to spatial data and information of the above ground, we lack the precise and detailed information about underground infrastructures, such as the spatial information of underground infrastructure, the ownership of underground objects and the interdependence of infrastructures in the above and below ground. How can we map reliable 3D underground utility networks and use them in the land administration? First, to explain the importance of this work and find a possible solution, this paper observes the current issues of the existing underground utility database in Singapore. A framework for utility data governance is proposed to manage the work process from the underground utility data capture to data usage. This is the backbone to support the coordination of different roles in the utility data governance and usage. Then, an initial design of the 3D underground utility data model is introduced to describe the 3D geometric and spatial information about underground utility data and connect it to the cadastral parcel for land administration. In the case study, the newly collected data from mobile Ground Penetrating Radar is integrated with the existing utility data for 3D modelling. It is expected to explore the integration of new collected 3D data, the existing 2D data and cadastral information for land administration of underground utilities.

Abstract:

Old tunnels suffer from deterioration and it is necessary to assess their residual strength to properly organize their repair and strengthen them. The stress state of underground structures evolves over time, firstly because of the advancement of the working face during construction, then due to gradual changes in soil properties and mechanical properties of materials composing the infrastructures, such as reduction of cohesion, loss of strength and (or) stiffness, etc. These changes are caused by combined actions such as creep and (or) weathering processes as well as the appearance of cracks that induce redistribution of stresses and therefore strains. This study investigates tunnels and galleries of the Paris underground. Macromodeling based on the finite element method allows consideration of different scenarios of tunnel-lining deterioration, specifically at the extrados of the galleries or tunnels. To understand changes in the stress state, and also damage occurrence and associated redistributions (stress and strain), it is necessary to model the delayed deformations. To model the infrastructure behavior, a time-dependency approach has been chosen. This approach can quantify the damage and predict the residual strength of this type of underground structure. An elastic–viscoplastic constitutive model with strain-softening is used to reproduce the appearance of the degraded zones and their behavior. The results obtained with the numerical approach reproduce Paris metro tunnel behavior, corroborate geoendoscopy results, clarify their interpretation, and improve the management of infrastructure repairs.

Abstract:

In recent years the issue of financing of infrastructure has become a critical issue and is widely discussed and in-depth reflection on policies, programs and development projects. The paper has the objective to describe one of the most interesting innovative methods of funding transport infrastructures: the mechanism of value capture, ie that capture (part) of economic benefits after the opening of the new infrastructure. The second part presents two case studies: the Quadrilatero Project and the Řrestad underground line in Copenhagen. The third part identifies success factors and criticalities about two experiences and offers some recommendations on the use of "capture value" as a mechanism of financing of transport infrastructure.

Abstract:

Purpose The purpose of this paper is to investigate the underground levels of a city to explore how vernacular and historic underground urban facilities help traditional cities to be sustainable. Therefore, the authors look at how culture, climate and economy affect those facilities. Design/methodology/approach The paper focuses on vernacular and local underground urban facilities in historic cities to find more sustainable processes of urban development that integrate cultural, climatic and economical concerns into design planning. The paper is based on a case study of the underground infrastructure of Dezful, Iran. Findings There are several vernacular building styles around the world, especially in Iran, with different shapes, materials, arrangements and concepts. Building construction has significant impacts on the environment and natural resources. Dezful is a city in Iran with a lot of potential in terms of its architecture. Vernacular cities possess infrastructure that helped them thrive in harsh climates. For instance, Dezful takes advantage of a systematic infrastructure termed the “Underground City.” Originality/value The traditional architecture of Dezful plays an important role in creating underground spaces, especially urban and architectural elements with thermal isolation properties that can be used as housing and as food storage. In this century, building construction could adopt these environmental properties, which could lead to low energy consumption in urban environments. Considering traditional and contextual elements in urban planning and design could revive sustainable community practices in urban environments.

Abstract:

The concept of sustainable development is receiving much attention throughout the global community. The concept embraces the traditional paradigm of infrastructure development and is expanding to a wider range of implications from social and environmental impacts caused by infrastructure development. Enhancement of sustainability is generally summarized using a triple bottom line approach of (i) minimizing environmental impact, (ii) maximizing economical benefit, and (iii) minimizing adverse social–cultural impact. Sustainability assessment should consider complications and interrelationships of all sustainability aspects throughout the entire life cycle. This paper presents a methodological development for a sustainability assessment modeling framework aimed at underground infrastructure construction projects. The modeling framework is based on assessing multiple proposed design alternatives and eliciting the most sustainable alternative through multiple assessment processes and a decision making process.

Abstract:

The power network is among the most of critical infrastructures. In Germany, multiple circumstances, triggered by social and political processes of decarbonization and nuclear phaseout, require extensive grid expansion activities. The paper analyzes coincidences of security and reliability aspects with transmission infrastructure planning. It explores essential properties that determine the criticality of power grids, examines to what extent security is subject of grid expansion procedures and finally focuses on selected security-related spatial planning issues such as the concentration of infrastructures or the pros and cons of overhead lines vs. underground cables.

Abstract:

Abstract High-voltage earthing system design is required to ensure safety compliance and adequate operation of the high-voltage infrastructures. The transmission lines form a solid part of the high-voltage infrastructure. The underground to overhead (UGOH) pole earth grid is one of the main challenges when it comes to transmission line earthing system design. To ensure safety compliance at low cost, counterpoise earthing is used at the UGOH pole for the underground lines. The counterpoise aids in lowering the UGOH pole earth grid resistance. This paper addresses the counterpoise analysis as currently being studied. Furthermore, it introduces the counterpoise mutual voltage between the faulted phase and the counterpoise and its impact at the UGOH pole earth potential rise. Case study is included.

Abstract:

Visualization of underground infrastructure in an interactive 3D immersive environment is extremely important for efficient management of city’s infrastructure. This paper describes different geometric modelling approaches to illustrate appropriate visualization of such data. A multimodal prototype has been developed by exploiting different algorithms to render these invisible underground objects as part of an urban model. This prototype has been integrated in an immersive geographic information system (GIS), named MultiVis, for handheld iOS and Android devices. As a part of the study, three distinct strategies have been tested; the first is based on the use of transparencies to convey a sense of depth, the second relies on an image-space superposition of “ditches” on top of the rendered frame and the third is a world-space deformation of the elevation model that exposes the underground elements. Furthermore, a comparative user experience analysis of different techniques aimed to the geometrically accurate visualisation of utility networks and other underground facilities are performed and evaluated. It includes a set of user evaluations for different parameters of these techniques, which gives us an insight on how the proposed methods affect the experience and usability for technical and non-technical users.

Abstract:

The development and utilization of complex underground space is an important way to establish the comprehensive transportation system and city disaster prevention space system in modern city. It is also one of the most important methods for building modern city infrastructure construction. This paper takes the city underground urban complex construction as the research object, studies the proper schematic of underground urban complex in core area of coastal city. The approach of making ground space into the underground approach in Qinhuangdao City is proposed. The target is to alleviate the city center area and create a good urban landscape.

Abstract:

The development of large cities presents unique social, political, and technical challenges. As a city grows in population, the limited area must accommodate people and infrastructure. Additionally, economic development attracts even more people to large cities. With limited surface land area, these cities must create space in the third dimension: upward and downward. Larger cities are already full of skyscrapers, and the underground is typically used for utility infrastructure, subways, road tunnels, car parks, warehouses, and sometimes for activities of human life such as shopping centers, meeting places, and art galleries. Some cities are exploring the use of the underground space for offices, schools, and even residential buildings.
