摘要

摘要本文提出了用拟静力法评价边坡对浅基础承载力影响的极限平衡法。采用粒子群优化技术对求解方案进行优化。本文以设计表的形式给出了边坡附近浅基础的最小承载力系数,以供岩土工程实际使用。结果表明,随着地震系数的增大,结构的抗震承载力系数明显减小。在两侧,随着边坡倾角的增大,承载力系数的大小进一步减小。

Seismic bearing capacity of shallow strip footing embedded in slope resting on two-layered soil
Abstract In this paper, the limit equilibrium method with the pseudo-static approach is developed in the evaluation of the influence of slope on the bearing capacity of a shallow foundation. Particle swarm optimisation (PSO) technique is applied to optimise the solution. Minimum bearing capacity coefficients of shallow foundation near slopes are presented in the form of a design table for practical use in geotechnical engineering. It has been shown that the seismic bearing capacity coefficients reduce considerably with an increase in seismic coefficient. Be sides, the magnitude of bearing capacity coefficients decreases further with an increase in slope inclination.

期刊介绍: An international journal ‘Studia Geotechnica et Mechanica’ covers new developments in the broad areas of geomechanics as well as structural mechanics. The journal welcomes contributions dealing with original theoretical, numerical as well as experimental work. The following topics are of special interest: Constitutive relations for geomaterials (soils, rocks, concrete, etc.) Modeling of mechanical behaviour of heterogeneous materials at different scales Analysis of coupled thermo-hydro-chemo-mechanical problems Modeling of instabilities and localized deformation Experimental investigations of material properties at different scales Numerical algorithms: formulation and performance Application of numerical techniques to analysis of problems involving foundations, underground structures, slopes and embankment Risk and reliability analysis Analysis of concrete and masonry structures Modeling of case histories
