摘要
现今构造特征在一定程度上体现了现今地应力场的分布。文中通过具体建立地质模型,结合川西坳陷的地质和构造运动特征确定模型的边界加载方式,运用ANSYS有限元软件,模拟出研究区现今地应力场的分布,通过对比分析并验证模拟结果,找到本区应力场的分布规律及其与构造特征的对应关系。
The present tectonic characteristics result from before regional tectonic movements, which cause to change of stress field. So remained tectonic stress will influence the distribution of the present stress filed while the tectonic characteristic can reflect the distribution laws of present stress field to some extent. In this paper , on the basis of constructing a geological model and deciding the loading way of boundary and selecting appropriate parameters, we can simulate the distribution of present stress field by using the software'ANSYS' and find the distribution laws of stress field. After checked the result, combined with the tectonic characteristics, the relation can be found between the tectonic characteristics and distribution rules of the present stress.
