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...

The geogrid and geocell with high tensile strength are meant to reinforce the mixture of natural gravel and recycled concrete aggregate made of the soild waste of construction. The reinforced cushion with variable stiffn...

There are problems when dealing with the dredger fills using the traditional vacuum preloading method, for example, the treated area can not be too large and the plastic-sheet maybe leaks. To solve these problems, the ne...

The unloading deformation and range of the excavation slope are larger in high-ground stress or soft rock areas, and the ordinary bolt (cable) cannot meet the need of such deformation. So, exploring the new support measu...

The earthen final covers based on the water storage and release principle have a promising application in the landfills in arid and semi-arid areas. Most of the previous studies concentrate on the rainwater infiltration ...

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...

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...

We analyse the radial pressure profiles, the intracluster medium (ICM) clumping factor and the Sunyaev-Zel'dovich (SZ) scaling relations of a sample of simulated galaxy clusters and groups identified in a set of hydrodyn...

By introducing the artificial intelligence technology, on improved Nelder-Mead acceleration algorithm based on the neural network is proposed to obtain better optimization results. A back analysis method for construction...
