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。
With the popularization of computer, geotechnical numerical calculation method has gained extensive attention in engineering field and has become a powerful calculation tool in geotechnical engineering analysis, design and monitoring. When the medium is non-linear, anisotropic, anisotropic or the boundary geometry and load more complicated, the analytical method is often very difficult, this time only numerical analysis. At present, the main numerical analysis methods are the finite difference method FDM, the finite element method FEM, the boundary element method BEM and so on. In this paper, the application of the finite difference method to the calculation and analysis of foundation settlement and the application of the finite element method in slope stability analysis are introduced firstly. In the end, the authors propose a systematic study on how to combine the monitoring data of foundation pit engineering with the software of numerical simulation to simulate the design and construction process so as to realize the transformation of the foundation pit engineering from the planar structure design to the space structure design, and then give more reasonable guidance Site monitoring to reduce project costs.
