With the further development of marine exploration in China in recent years, higher requirements are put forward for the capacity of the soil and cyclic loading effect for the offshore engineering. Due to the difficulty ...

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...

Based on the complete researches on rock burst, the prevention and control situations and development tendency of rock burst are analyzed. The prevention and control idea of high stress and high energy rock burst is put ...

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 HS-Small model, which can reflect the attenuation of shear modulus of soils with strain in tiny strain range, has been gradually utilized in excavation engineering. The laboratory tests using triaxial apparatus, oedo...

The impact roller (IR) compaction method is an efficient and cost-effective compaction technique, which has been widely used in highway and airport engineering for subgrade compaction and ground improvement of soft found...

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...

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...

A refinement method is proposed to solve the difference in the macroscopic elasticity and the interpenetration in interface area between different particle-size areas in the DEM. In simulations of 3D DEM large-scale prob...
