摘要
根据已有的地质资料、所测得的岩石力学参数及建立的地应力分布模型,采用三维有限差分程序FLAC3D对河北某矿地表及岩层移动进行数值模拟研究,分析了采场最大主应力场、最小主应力场、破坏场和位移场的分布特征,圈定出了最终的地表塌陷边界。
Based on the obtained geological data and rock mechanics parameters as well as established ground stress distribution model, three-dimensional finite difference program FLAC^3D was used to conduct numerical simulation of ground surface and strata displacement of a mine in Hebei. The distribution characteristics of maximum principal stress field, minimum principal stress field, destruction field and displacement field were analyzed. The final ground surface subsidence boundary was determined.
