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...

Soft clay is influenced by the time-dependence of viscosity and consolidation as well as coupling effect of moisture. In order to study the effect of moisture content on soft clay foundation, by introducing the elastic-v...

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...

A large-diameter steel tube pile is used in a machinery factory in Shanghai to test the new produced diesel pile hammer. However, with the increase of the diesel hammer weight, it fails to meet the test requirements and ...

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...

Hongyang Substation is combined with the upper part of the building of deep buried underground substation, and it can well solve the contradictions between urban electricity and land use tension. However, in power system...

The analytical solutions are presented for the sequential excavation of the tunnel with any shape in viscoelastic rock subjected to anisotropic stress conditions. The complex variable method and the Laplace transformatio...

Considering the heterogeneity characteristics of concrete materials, the method of the mesoscopic mechanics is used to investigate the dynamic damage of slabs of concrete face rockfill dam (CFRD) combined with the statis...

The inherent variability of soil properties has currently received considerable attention in slope reliability analysis. However, the geological uncertainty is often ignored in analysis. This paper proposes a method for ...
