-
摘要: 运用岩体工程地质力学方法和数理统计原理,建立了初始地应力场的三维有限元反演及回归分析模型。该模型克服了边界调整法等一般反分析法的不足,具有很好的实用价值和易操作性,能够方便较为准确地反演区域初始地应力场。Abstract: Based on rock mass engineering geomechnical theory and probability and statistics for engineering, establish a 3-D FEM back-analysis and statistics regression analysis model for in-situ crustal stress field. The model overcomes the shortcomings of the boundary loading adjustment method etc .It is practicable and easily manipulated, which can back-analyze the region situ crustal stress field quickly and accurately.
