摘要
应用复杂地质体极限平衡理论,研究了东明凹陷地质构造力学成因机理.通过地震勘探、钻井资料,分析了东明凹陷所处区域地质背景、区内地层沉积特征、岩浆活动、构造展布规律等.用滑移线场模拟了断陷盆地几条典型剖面.在力学解析中考虑层状地层各向异性等因素,将计算所得滑移线拟合实际断裂构造,拟合效果较好.
A mechanical analysis of the geological structure of Dongming Depression is conducted by applying the limit equilibrium theory of complex rocks. The regional geology, strata, magmatism and structure are all studied. Some typical sections are analysed. Fractures are simulated with slip line field. Rock anisotropy is taken into account in the theory of this paper. The real geological structure is simulated very well with this theory.
