摘要
在分析总结地质构造与地应力方向关系的基础上,采用有限差分数值模拟软件FLAC3D,建立了分析褶曲、断层等常见地质构造的数值模型.分析了地质构造附近岩层位移、应力场分布特征与变化规律,以及岩层破坏状况,模拟结果与理论分析相一致.
Based on the analysis to the relations between geological structures and the in-situ stresses, the numerical models was set up for analysis on the normal geological structures, such as folds and fault using finite difference numerrical simulation software FLAC^3D. The strata displacement, stress fields distribution and variation law, the strata damage states in the vicinity of the geological structures were analysed. The numerrical simulation results are consistensied with those of theory analysis.
