中文摘要: 在深入探讨皮羌走滑断裂对构造裂缝控制作用的基础上,应用ANSYS有限元方法,模拟区域差应力、走滑断裂宽度和走向等因素影响下构造裂缝分布发育的规律。模拟结果表明,构造裂缝带宽随区域差应力增大呈线性增大,随断裂带宽度增大呈线性减小,随断裂走向与区域差应力夹角增大呈线性减小;施加的区域差应力值是影响构造裂缝发育的主要因素。

Abstract:Based on the intensive research on development of structural fractures that controlled by the Piqiang strike-slip fault, this paper has simulated the distribution of structural fractures under the influence of the regional deviatoric stress, the width and trend of the strike-slip fault through the "ANSYS" finite element method. The simulating results indicated that the width of the fractures increased linearly with the increase of the regional deviatoric stress, decreased linearly with the increase of the width of the faulted belt, and decreased linearly with the increase of the angle between regional deviatoric stress and the fault trend. The regional deviatoric stress is the main factor that controls the development of the fractures.
