数值方法在解决地下洞室围岩稳定问题中越来越发挥着重要的作用
本文采用FLAC3D数值分析方法,全面分析了地下洞室开挖完成后围岩的二次应力场、变形场的变化规律和塑性破坏区的分布特征
地下洞室
Boundary condition can be considered
In this paper, it analyzed and evaluated the change character of the second stress field and deformation field and distributing character of the plastic zone in the course of the underground cave’s excavating by use of the program FLAC3D
The result can provide certain instructional significance to the design and construction of engineering

） Abstract： With the wide application of computer, numerical analysis for the stability of underground
Cavern has Played a more and more important role
With numerical method
complicated geologic condition
数值方法能够较好地考虑诸如介质的各向异性、非均质特性及其随时间的变化、复杂边界条件和介质不连续性等复杂地质条件
