Macroelement modelling of caisson foundation in clay

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

The purpose of this study is to model the caisson in clay from a complete finite element analysis to a simplified microelement modeling. First, the fi......

Study on large rotation problem of a block in discontinuous deformation analysis

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

The original discontinuous deformation analysis (DDA) takes the first-order approximation of the incremental displacement to update block configuratio......

Mesostructure modeling for rock and soil based on ellipse packing with multiple prescribed distribution

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

Natural rock and soil have complex mesostructure and composition characteristics, and it is difficult to model geotechnical mesostructure, which has s......

Microseismic evolution of rock mass with staggered zone of underground intersecting chambers under excavation disturbance

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

Staggered zones have the properties of "multiple shear dislocation in history, wide range, easy to soften when exposed to water and low mechanical str......

Stability analysis of high dump with wide graded waste rock

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

The high-bench dump of wide-graded waste rock formed by slope-to-the-bottom has obvious particle size grading characteristics. Traditional stability a......

Design method of the thermosyphon embankment in permafrost region based on principle of heat balance

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

Thermosyphon is one of the important measures for thermal protection of the embankment in permafrost region. But the design method of the thermosyphon......

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

In order to study the formation and development mechanism of surface subsidence in Chaganaobao iron-zinc mine, Rongguan mining industry, Inner Mongoli......

Landslide monitoring based on point cloud density characteristics

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

It has been realized that the points collected twice by the laser scanner for the same target do not coincide, and the landslide displacement cannot b......

A study on the calculation method of horizontal displacement of adjacent tunnels caused by static pressure sinking piles

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

In the process of static piling, there will be a strong soil squeezing effect, which will cause disturbance and deformation of the soil around the pil......

A new anti-float method for riverside underground structures: drainage corridor combined with uplift piles or uplift anchors

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

The riverside groundwater level has a unique characteristic of low for long term working conditions but extremely high during flood seasons. This char......

Simplified calculation method for lateral pressure at rest in the under-consolidation stratum

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

Lots of practical projects have revealed that the accurate calculation of lateral pressure at rest in the under-consolidation stratum plays a crucial ......

Analytical solution to saturation line of tailings pond and its applicability analysis

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

At present, the saturation line of a tailings pond is mostly solved by the method of numerical simulation or model experiment, and there are few analy......

Calculation on the settlement of dredged slurry treated by vacuum preloading method with consideration of clogging effects

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

The dredged slurry has high water content and very low strength. It is generally considered that there will be no smear effect when the PVD is inserte......

Centrifuge shaking table modelling test study on anti-liquefied densification of small earth-rock dam slope

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)

The liquefaction of small earth-rock dam slope under earthquakes is easy to cause serious consequences, such as instability and sliding of the dam slo......

A method for evaluating the unloading disturbance and sample quality of marine gas-bearing sediments based on shear wave velocity

期刊: ROCK AND SOIL MECHANICS, 2020; 41 (11)
