摘要
地质动力区划方法逐级使用地形测量图并结合其它方法查清活动断裂,用以揭示地壳的区域岩体断块结构以及评估其力学状态。通过地质动力区划方法查明了红菱井田现今应力环境下的Ⅱ~Ⅴ级断裂,由各级活动断裂所分割的断块结构展现出了井田现今构造运动的结果。在确定主应力的基础上,以查明的各级断块结构为模型,应用有限元法进行了区域构造应力场数值模拟,进而分析了该井田以构造应力为主的地应力特点。
Geodynamic zoning is used to determine active faults successively with topographic map and other methods, and to reveal regional block construction of rockmass in the crust, and to evaluate their mechanical conditions. Some classⅡ~Ⅴactive faults that run through Hongling mine field in modern stress environment are found out by means of geodynamic zoning. The block constructions cut by all classes of active faults exposes the result of tectonic movement. Based on determining the principal stress, this paper has made numeric simulation of regional tectonic stress field, and the paper has analyzed the crustal stress characteristic of the mine field which is mainly tectonic stress, by the model built on all classes block constructions and the finite element method.
