The heart-shaped stress path can be caused by train loads in the foundation. The train load path has a more complicated influence on foundation soils when the effects of frequencies are considered. A serious of undrained...

Four groups of centrifugal model tests are performed to investigate the failure mechanisms of embankment on inclined soft foundation reinforced by CFG piles. The tests simulate four kinds of grounds: natural inclined sof...

Four groups of centrifuge model tests are performed to investigate the failure mechanisms of embankment on inclined soft foundation reinforced by pipe piles. The influences of embedded depth of pile toe into stiff stratu...

Sandbag cofferdam applies flexible load on soil foundation. The failure mode and sliding surface of soft soil foundation under sandbag cofferdam should be significantly different from that under rigid base. Aimed to get ...

In view of the collapse accidents encountered in the process of tunneling in weak and fractured rock mass, scaled model tests and numerical simulations are developed to study the progressive failure process of surroundin...

The voids behind the tunnel linings seriously affect the interaction between the linings and the surrounding soils, generally in the form of cracking, spalling or even failure, directly affecting the safety of tunnel ope...

By using the method of model tests and introducing the progressive failure theory into the analysis of disease occurrence and propagation of segment linings of shield tunnels, from the internal force, structural displace...

Abstract Sirtuin 1 has an important role in cellular processes, including apoptosis and cellular stress. The purpose of this study was to assess serum sirtuin 1 levels in women with recurrent implantation failure (RIF). ...

The conventional stability design method for the composite ground improved with rigid piles (CGIRP) to support embankment assumes a simultaneous shear failure of the piles with the failure slip. Based on the previous stu...

The stability analysis methods for composite foundation improved by rigid piles under embankment are imperfect at present. The finite element method is used to analyze the damage process and failure mode of the piles und...

In deep excavations with a large area of soft soil, the multi-bench retaining method, which has a short construction period and doesn’t need any horizontal reinforced concrete struts, can be used to replace the method ...

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...

The saturated permeability coefficient of soil is an inherent variable due to its inhomogeneity and the inaccuracy of monitoring. To explore the stability and failure probability of bedrock laminar slope under heavy rain...

Numerical analysis of basal upheaval stability of foundation pits is a very important method in researches on deep excavation engineering, which is in the initial development stage and is of important issues remained to ...

The traditional failure mechanisms with constant shapes usually overestimate the basal stability of excavations in clay. A new mechanism is established based on the upper bound theorem. The least upper bound solutions an...

The approach for calculating the ultimate bearing capacity at the tip of rock-socketed pile in karst areas is proposed considering the coupled bearing effects of rock of socketed part and cavity roof, as well as the infl...

A small-scale physical modelling system is developed to study the pull-out mechanism of embedded soil nails based on transparent soil and particle image velocimetry (PIV). Four types of soil anchorages, common cylindrica...

The experimental tests are carried out on the strength and deformation characteristics of four typical rock samples of phyllite taken from the northern tunnels of Longmen Mountains of the Chengdou-Lanzhou Railway. The re...

In order to study the influence of non-uniform distribution of fine soil on mechanical properties of coarse-grained soil under freeze-thaw cycles, triaxial shear tests are conducted on different specimens with different ...

There is local shallow and strong permeable stratum in dike (dam) foundation, and its head dissipating capacity is weak. It is easy to cause piping failure, and the failure mechanism still needs further studies. The eros...
