The excavation construction of twin parallel tunnels is simulated by using centrifugal model tests. The internal stress and deformation variation of shield structure of the existing tunnel and the ground surface settleme...

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...

Since the coefficients of variation of soil properties vary in a large range, the real reliability index for the soil slope designed using the partial factor method also fluctuates in a range. This drawback limits the ap...

In order to obtain the criteria and precursor characteristics of critical rock fracture, laboratory experiments on the characteristics of acoustic emission (AE) of gritstone specimens under uniaxial compression are carri...

The shear modulus and damping ratio of EPS composite soil, as a kind of artificial filling material, are the key parameters to analyze the dynamic stability of embankment. 15 cyclic torsional tests are conducted on the h...

Based on the thin plate theory and the elastodynamics theory, the mechanical analysis model and the dynamic differential equations for the infinite elastic plate on orthotropic foundation under moving harmonic loads are ...

obvious influence on the failure strain than on the initial yield strain. The non-uniform distribution of fine soil has a more significant influence on the initial yield strain than on the failure strain. Key words: fi...

Based on theoretical analysis, the spectral element method is used to study the effect of bedrock terrain on ground motion. The achievements are as follows: (1) The intensity of bedrock ground motion is related to bedroc...

Soil acidity is one of the reasons for corrosion of steel piles. The material deterioration of steel pile foundation served in the acidic soil will affect the safety and durability of pile foundation. In order to underst...

The property of the soil in free field is an important influencing factor for the free field seismic response. In the existing studies the soil at local site is supposed to be the single-phase medium or saturated porous ...

There is not a consistent conclusion on the influences of loading frequency on dynamic modulus and damping ratio, and the quantitative results are few. Through a series of tests using the new cyclic triaxial (CT) divice ...

Using the ring shear apparatus, the variation rules of residual strength of 17 saturated claysoil samples with different plasticity indices under different consolidation conditions are studied. The influences of current ...

The large-strain self-weight consolidation theory is widely used for the design of dredged material disposal sites and the treatment of hydraulically dredged slurries in the disposal sites. The self-weight consolidation ...

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...

Qwing to that the common cement paste used in the complex soil strata with wide steep seams and loose space cannot fill firmly and run along the gaps, a new type of SJP cement paste is developed, which has great initial ...
