本文推导了分歧理论的通用表达式,在其基础上结合有限差分理论推导出FLAC3D计算中岩土体内发生分歧的判定条件,之后在自带的FISH编译语言的辅助下在FLAC3D中研究岩体局部化现象及其发展过程。研究结果非常理想:模型系统逐渐趋于稳定(不平衡力比率在降低)过程中,局部化现象的规模逐渐扩大至稳定,清晰度逐渐增加,证实分歧理论能够有效地分析研究岩体局部化现象。
In this paper, the general expressions of divergence theory are deduced. Based on the finite difference theory and the finite difference theory, the conditions of disagreement in rock and soil mass in FLAC3D calculation are deduced. Then the local part of rock mass is studied in FLAC3D with the aid of FISH compiled language Phenomenon and its development process. The results are very satisfactory: the model system is gradually stabilized (the ratio of unbalanced force is decreasing), the scale of localization gradually expands to stability and the definition increases gradually, which confirms that the disagreement theory can effectively analyze and study the phenomenon of rock mass localization .
