Through numerical simulation based on the particle flow method, DEM numerical test samples are generated in accordance with the results of laboratory tests on standard sand. Using gravity deposition modelling of irregula...

Jacking force is one of the crucial parameters to decide design of pipe structure, selection of pipe jacking meachines and design of shaft structure for jacking projects. In order to more accurately calculate the jacking...

To simulate the joint network around mining tunnels and to conduct the stability analysis of tunnels in jointed rock mass, a numerical model for jointed rock mass containing particle flow block model, original joint netw...

Volume changes take place during the fully undrained compression tests on unsaturated soils. It is more difficult to simulate the undrained mechanical behaviors of unsaturated soils than those of saturated soils. In this...

In order to investigate the performance of with embankment slopes reinforced waste tires and geocells, the model tests on reinforced the embankment slopes with waste tires and geocells are carried out respectively, and t...

The statistics of uncertain rock and soil parameters can be updated with the information from different sources such as in-situ measurements and field observations via probabilistic back analysis, which can be further us...

In order to study the earthquake seismic behaviors of ecological bags-reinforced wall, the large-scale shaking table model tests are performed. It is shown that the frequency decreases and the damping ratio increases wit...

Considering the heterogeneity characteristics of concrete materials, the method of the mesoscopic mechanics is used to investigate the dynamic damage of slabs of concrete face rockfill dam (CFRD) combined with the statis...

The safety of core wall type rockfill dams during reservoir impounding is greatly affected by the slaking deformation of upstream shell materials. The slaking deformation of the rockfill materials is analyzed using the t...

In order to observe the effected strip of geogrid-reinforcement, a series of geogrid pull-out tests are conducted in a test box which has one Plexiglas wall, applied 4 different vertical pressures on each specimen prepar...

In order to verify the reasonableness of two stress state variables for unsaturated soils and to improve the accuracy of tests, the triaxial apparatus for conventional unsaturated soils has been improved to control the p...

Based on the framework of thermodynamics and critical state soil mechanics, a new α-β yield surface is formulated in the triaxial space. Based on the non-associated flow rule and bounding surface framework, the propose...

Based on the SMP criterion-based K0 consolidated anisotropic Cam-clay model, an analytical solution to cylindrical cavity expansion for pile installation is derived. This solution incorporates the effects of the initial ...
