摘要
本文叙述了在三峡工程8号勘探平洞中利用有限元和复变函数计算方法进行位移反分析的计算成果,并与地应力和位移实测值作了比较,对围岩应力场和位移场作了分析。同时也介绍了这两种方法的原理和基本公式。
This paper relates the results of back analysis calculation of displacement measurement utiliz ing finite element method and complex variable function method on Three Gorges Project, comparing with measured values of geostress and displacement. The stress and displacement fields of surrounding rock are analysed. It also presents the principls and basic formulas of both methods.
