岩体材料参数反分析的有限元方法研究

Research of finite element method in back analysis of anti-rock parameter

本文主要研究讨论了工程反分析和岩土工程中关于求解材料力学参数的方法,在岩土工程中称为反分析法。一般来说,反分析问题比正分析问题要困难得多。经验表明,有限元法是反分析的有力工具。反分析目前有多种方法,本文着重讲述了逆反分析法。

This article discusses the major research project back analysis in geotechnieal engineering and materials on the mechanical parameters for solving approach, in geetechnical engineering as anti - analysis. In general, the back - analysis than analysis d the problem is much more difficult. Experience has shown that the finite element method is a powerful tool for counter - analysis. There are a variety of back - analysis method, described in this paper： displacement method, inverse analysis.
