Using specially designed low-temperature resonant column apparatus, change rules of dynamic shear moduli and damping ratio with negative temperature and their computational methods for three soils are investigated. Conce...

As an isolation barrier between landfill and atmospheric environment, monolithic covers are used to control rain water infiltration and deep percolation into landfill. In recent years, the covers are proved to be effecti...

The constraint conditions at pile head are assumed based on the case of Zhejiang Hotel Expansion Project, and then the deflection functions under different constraint conditions of pile tip and top are introduced. The to...

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...

The anti-plane dynamic stiffness coefficient of a rigid foundation embedded in a multi-layered transversely isotropic (TI) ground is obtained by using the indirect boundary element method (IBEM). Firstly, the interface o...

In recent years, the distributed fiber optic sensing technology has become a new tool in the research area of geotechnical tests and measurements and played an increasingly important role in deformation monitoring of geo...

A hybrid technique, FEM-IBIEM is developed for studying the scattering of seismic waves by a 3-D complex local site. The indirect boundary integral equation method (IBIEM) adopts the dynamic Green's functions of concentr...

The tests are performed to study the gas permeability of unsaturated intact Q3 loess with various water contents under different isotropic stresses using the improved triaxial gas permeability equipment. The influences o...

The in-situ measurement formula for rock permeability is derived based on the theory of steady gas seepage. A rough judgement method for Darcy seepage in engineering is given based on the Pavlovsky’s Reynolds number fo...

Basalt fiber is a kind of inorganic material, which is effective and environmentally friendly. Basalt fiber concrete has important mechanical advantages to control the deformation of soft rock tunnels because it has func...
