Abstract:

Bro 2004, BV Bro and the Eurocodes give guidelines for how to consider earth pressure induced by change in temperature and braking forces when designing backwalls. In this thesis those demands are investigated using PLAXIS for evaluation of the earth pressure. The results show that the model in PLAXIS corresponds quite well with the conventions in Bro 2004 and that modelling in PLAXIS gives reliable results. The demand in Bro 2004 that backwalls always shall be designed for passive earth pressure has been found to be pessimistic. In case of long bridges and short backwalls passive earth pressu

Abstract:

A soil-steel composite bridge is a structure comprised of corrugated steel plates, which are joined with bolted connections, enclosed in friction soil material on both sides and on the top. The surrounding friction soil material, or backfill, is applied in sequential steps, each step involving compaction of the soil, which is a necessity for the construction to accumulate the required bearing capacity. Soil-steel composite bridges are an attractive option as compared with other more customary bridge types, owing to the lower construction time and building cost involved. This is particularly tr

Abstract:

Shallow foundations are extensively used to support structures of all sizes in order to safely transmit the structural load to the ground without exceeding the bearing capacity of the ground and causing excessive settlement. They are typically embedded up to a few meters into the soil profile. While designing foundations, two requirements need to be satisfied: complete failure of the foundation must be avoided with adequate margin of safety (bearing capacity) and relative settlement should be within limits that can be tolerated by superstructure. Foundation is that part of the structure which

Abstract:

The monopiles with typical diameters of 4-6m are mostly used as foundations for the offshore wind turbine structures to resist the vertical and horizontal loads. The response of the laterally loaded pile depends upon the soil and pile behavior and also on the interaction between them. Various methods for the development of p-y curves exist and the accuracy of such methods depends upon the data from which it was developed. The accuracy of the analysis of the pile depends on the accuracy at which the p-y curve represents the soil response to the lateral pile deflection because most of the common

Beräkning med finita elementmetoden, FEM, är en vanlig metod vid lastnedräkning för bärande konstruktioner. Vid FEM-modellering inom huskonstruktion måste konstruktören på något sätt även modellera markens egenskaper för att uppnå statisk jämvikt i modellen. Att låta byggnaden vila på oeftergivliga stöd fungerar vid grundläggning på berg, men i övriga fall måste jordens deformation vid belastning simuleras. Ett vanligt tillvägagångssätt är att konstruktören samarbetar med en geotekniker som beräknar sättningar i jorden utifrån de laster konstruktören beräknat. Det görs i ett geotekniskt FEM-pr

In dense cities, the interactions between all structures, from tall skyscrapers to complex underground tunnel systems, need to be carefully analysed as soon as a new project is considered.

Embankment dams encounter several problems in terms of dam safety. One of those problems is called internal erosion. This phenomenon is induced by the movement of fine particles within the dam due to seepage forces. If the dam is not able to self-heal, the eroded zones will increase which will eventually cause the dam to fail. Thus standards have been created by Svensk Energi and summarized in the Swedish dam safety guideline RIDAS 2012.

Abstract:

In mechanized tunneling the annular gap between the segmental lining and the surrounding soil caused by tunnel driving must be backfilled instantaneously with an adequate mortar. The annular gap is caused due to the conical shape, overcut and design of the shield. The soft ground tunneling has a prime focus on the settlement control and optimization of the parameters involved. The backfilling is a key component to reduce the surface settlements and deformations after the passage of the TBM. The main functions of backfilling are to 1. lock the segmental lining in position avoiding movements

Applicering av överlast på kalkcementförstärkta jordar är ofta förekommande idag, forskning indikerar dock på att överlasten här, inte ger samma effekt som på oförstärkta jordar. Med grund i uppmätta värden i fält, visas i denna rapport, sättningsdifferenser mellan att använda överlast jämfört med att endast applicera brukslast. Resultat av analyserna visar på sättningsbeteende observerat i fält. Om erforderlig liggtid för brukslast finns, uppstår endast små sättningsdifferenser mellan att använda överlast eller inte. Genom att utföra sensitivitetsanalys i FEM- programvaran PLAXIS studeras kry

Abstract:

Den finkorniga sulfidjorden som finns längs Norrlandskusten är känd för sin stora sättningsbenägenhet och utgör en potentiell miljörisk genom försurning och urlakning av metaller om den inte hanteras rätt. För att förebygga miljörisker och utveckla jordförstärknings- och grundläggningsmetoder måste en ökad kunskap om sulfidjordar tas fram. I ett pågående forskningsprojekt vid Statens Geotekniska Institut studeras sulfidjords kompressionsegenskaper och rekommendationer ska tas fram avseende underlag för sättningsberäkningar. I projektet omfattas ett antal provbankar där ett av dessa områden, La

Abstract:

The need of exploring efficient solutions to today’s engineering problems is becoming essential in the current market development. Soil Steel composite bridges (SSCB) are considered well competitive in terms of their feasibility and constructability. The primary objective of this study is to provide a comprehensive comparison study for two known design methods of SSCB, which are the Pettersson-Sundquist design method (developed in Sweden) and the Klöppel & Glock design method (developed in Germany). Moreover, in the goal of having better behaviour understanding for SSCBs, the study also in

Abstract:

Il crescente aumento di eventi di precipitazione intensa è causa della sempre più diffusa presenza di fenomeni di erosione retrogressiva sotto le strutture arginali: i fontanazzi, che generalmente si formano in prossimità del piede arginale, sono la manifestazione esterna del verificarsi di tale fenomeno. Questo tipo di erosione interna, se non contrastato, può determinare il collasso dell’argine, con conseguenze ovviamente catastrofiche per l’ambiente circostante. Per questa ragione, negli ultimi decenni si è assistito ad un crescente interesse nei confronti dello sviluppo di strategie di

Abstract:

Wind farm construction is increasing progressively, to cope-up with the current global energy scenario. The advantage of clean energy and sustainability helps wind turbine construction to flourish rapidly. Location of wind turbines is independent of foundation soil condition but depends on the wind speeds and socio-environment issues. Hence, a construction sites may not be favorable in terms of geotechnical demands. The taller wind towers facilitate the generation of high energy production, which will increase loads on the foundation, and eventually increase the dimension of the foundation. He

Abstract:

During the casting of a concrete bridge deck, the temporary formwork is causing the underlying ground to deform if a shallow foundation solution is used. There are often demands on the maximum deformation of the superstructure when designing the foundation for the formwork. To keep the deformations within the desired limits, several ground improvement methods like deep mixing columns or deep foundation methods like piling can be used. Permanent ground improvement methods are however expensive, and far from always needed. To reduce the need for unnecessary ground improvements, it is crucial to

There are approximately 20 000 small dams in the Czech Republic. This number entails many ponds or small flood attenuation reservoirs, which provide protection against floods. We do not know much about the structure and material properties of these earth dikes. Concerning the small dam stability the current technical standard ČSN 75 2410 focuses foremost on the angle of both the upstream and downstream slopes in case of different materials, and the method of the stability assessment in case of a dam height being 6m or more. Most of these earth dikes are still standing in spite not being built
