【摘要】 岩土工程数值计算方法随着计算机的普及而得到了工程界的广泛重视,已成为岩土工程分析、设计和监测中的强有力的计算工具。当介质为非线性、非均质、各向异性或者边界几何形状与荷载较复杂时,解析法往往困难很大,此时只能用数值分析法。目前主要的数值分析方法有有限差分法FDM、有限单元法FEM、边界单元法BEM等。本文首先结合已有工程案例介绍有限差分法在地基沉降计算分析中的应用,以及有限元法在边坡稳定性分析中的应用。最后提出作者下一步准备系统研究的一项工作,即如何结合基坑工程监测数据,利用数值软件模拟设计施工过程,实现基坑工程由平面结构设计向空间结构设计的转变,进而更加合理的指导现场监测工作,减少工程造价。更多还原

【Abstract】 With the popularity of computer, numerical simulation has become widely appreciated by the geotechnical engineers. It also become a powerful analysis tool in the geotechnical engineering. Such as, when the medium is nonlinear, heterogeneity and anisotropy or boundary geometry and load are complicated, analytic methods are often very difficult. At this time can only use numerical analysis method. At present, the main numerical simulation methods include FDM,FEM and BEM. In this paper, the application of FDM on the calculation of foundation settlement was first introduced, and then analysis the slope stability through FEM combined with the existing engineering cases. How to combine the foundation pit engineering monitoring datas, simulating the design and construction process by using the numerical simulation software to realize the space structure design and make more reasonable field monitoring work in pit engineering will be a new subject.更多还原
