Abstract:
The joints in the rock mass are essential for the stability of rocky slopes, and the destabilization damage of the slope is often directly related to the joints. In this study, in order to reveal the instability process and mechanism of rock slopes from a microscale perspective, the DEM simulations for rocky slopes of the K88 + 400∼K88 + 540 section of Zhongkai Expressway are carried out considering the influence of joints. Based on the findings of the on-site jointed structural surfaces, a rocky slope model containing two sets of intermittent joints was constructed, and the linear parallel bo

Abstract:
Excluding rough areas with surface rocks and craters is critical for the safety of landing missions, such as China’s Chang’e-7 mission, in the permanently shadowed region (PSR) of the lunar south pole. Binned digital elevation model (DEM) data can describe the undulating surface, but the DEM data can hardly detect surface rocks because of median-averaging. High-resolution images from a synthetic aperture radar (SAR) can be used to map discrete rocks and small craters according to their strong backscattering.

From the distribution of aspect ratios, a total of 16 groups of shapes have been created.

Abstract. Karst rocky desertification (KRD) is used to characterize the processes that transform a karst area covered by vegetation and soil into a rocky landscape almost devoid of soil and vegetation. This situation seriously affects and threatens the living environment and standards of local people, which results in a series of social problems. In view of the importance and harmfulness of KRD, many scholars have studied the spatial and temporal evolution of KRD and its driving forces.

A list of assumptions and boundary conditions necessary for modeling the process of wet semi-autogenous grinding by the finite element method is presented.

Over the last century, numerous practitioners and researchers have investigated the particle behaviour of granular soils based on laboratory testing, to improve their knowledge of strength qualities. The discrete element modelling (DEM) technique has been commonly used to improve the understanding of granular soil behaviour.

Shortening by about 70 km derived from balanced sections across the Zagros folded belt, yields shortening rates of 7 km Ma-1 consisten

River blockages formed by rock avalanches appear to pose a higher hazard potential than other landslide dams, given the extreme run-out distances and volumes of rock avalanche deposits. Recent research has identified rock avalanche deposits to have internal sedimentology consisting of a coarse surficial material (carapace) and a finer fragmented interior (body) potentially of critical importance to rock-avalanche dam stability. Physical scale modelling of overtopping failure and breach development in rock avalanche dams was used to quantify the influence of this sedimentology on critical breac

To a large extent, mining is a waste management business. In most mining operations, metal resources are found in host rocks at concentrations of a few percent or less, resulting in the production of large quantities of wastes during metal extraction and processing. These wastes can occur in the form of bulk waste rock, and fine-grained material (tailings) that remain after the ore is ground and processed. The two principal mine-waste management challenges are the containment of tailings, and the management of contamination leaching from tailings and waste rock. Over the past decade, several h

The Vernal NE 7.5' quadrangle is located at the northern boundary of the Colorado Plateau physiographic province, within the Uinta Basin sub-province (Fenneman and Johnson, 1946). The Middle Rocky Mountains, in Fenneman and Johnson’s (1946) classification, is located east and north of the quadrangle. The quadrangle includes Ashley Valley, centered on Ashley Creek, which drains the southern flank of the Uinta Mountains. The western part of the quadrangle is defined by the northwest-southeast-trending Asphalt Ridge and the west-dipping slope along the flank of the ridge. The northeastern part of

Abstract:
Evaluating the seismic performance of concrete dams requires nonlinear dynamic analysis of two- or three-dimensional dam–water–foundation rock systems that include all the factors known to be significant in the earthquake response of dams. Such analyses are greatly complicated by interaction between the structure, the impounded reservoir and the deformable foundation rock that supports it, and the fact that the fluid and foundation domains extend to large distances. Presented in this report is the development of a direct finite-element (FE) method for nonlinear earthquake analysis of two- and

Abstract:
We present a systematic investigation of computational approaches to the modeling of granular materials. Granular materials are ubiquitous in everyday life and in a variety of engineering and industrial applications. Despite the apparent simplicity of the laws governing particle-scale interactions, predicting the continuum mechanical response of granular materials still poses extraordinary challenges. This is largely due to the complex history dependence resulting from continuous rearrangement of the microstructure of granular material, as well as the mechanical interlocking due to grain morph

Abstract:
A physical model study of the LaGrange Lock and Dam was conducted to optimize the navigation conditions for the new landside lock chamber design developed by the US Army Corps of Engineers–Rock Island District, Inland Navigation Design Center, and Stanley Consultants. A 1:120 Froude scale model was built to evaluate the navigation conditions for tows entering and exiting the upper and lower approaches. The final design consisted of a new 1,200 ft lock chamber located landward of the existing chamber. Data were collected to evaluate tow tracks and current direction and velocity information. Sat
