为了研究地质构造周围应力分布,结合某石膏矿-400m水平地质构造条件,建立三维数值计算模型,对地质构造周围的应力进行了分析。研究结果显示:断层F17周围存在较大压应力,断层F18附近存在拉应力,其他断层以拉应力为主;在地质构造中的最大压主应力值为5.20MPa,最大拉主应力值为3.43MPa;拉应力矢量主要分布在石膏矿体靠近断层附近。
In order to study the stress distribution around the geological structure, combined with the -400m geological conditions of a gypsum mine, a three-dimensional numerical model is established and the stress around the geological structure is analyzed. The results show that there is a large compressive stress around the fault F17 and tensile stress near the fault F18, and the other faults are mainly tensile stress. The maximum principal stress of the geological structure is 5.20MPa and the maximum principal stress is 3.43MPa The tensile stress vectors are mainly distributed near the gypsum ore body near the fault.
