摘要: 光滑质点流体动力学(简称SPH)是一种纯Lagrangian、无网格的流体动力学计算方法,已经广泛应用于与工程相关的许多学科的计算分析研究中。鉴于岩土工程中的SPH方法的研究应用是一个比较新的研究方向,首先简述了SPH方法在岩土工程应用的基础,重点讲述了目前SPH方法在岩土工程相关学科中的应用,最后针对地震液化问题,提出未来可以将SPH方法运用到地震液化前后变形特征的统一分析中,以及借鉴爆炸和冲击科学中SPH-FEM耦合方法进行地震液化中结构物破坏机理的研究。Abstract: SPH(smoothed particle hydrodynamics) method,a pure Lagrangian,meshless hydrodynamics method,has been widely applied in numerical simulations in many engineering fields.Since SPH method was a newly emerged method for the applications in the geotechnical engineering fields,the basic concept was firstly introduced concerning the researches in geotechnical engineering.Then the emphases were put on the numerical simulations in the fields relative to geotechnical engineering with SPH method.Moreover,as far as the researches on seismic liquefaction were concerned,it was proposed that the deformation characteristics in the pre-and post-liquefaction process should be generally analyzed in the frame of SPH method,and the mechanism of structure failures in liquefaction should be considered with coupled SPH-FEM methods which were verified in explosion and impact science.
