南水北调西线工程断裂位移随深度变化的数值模拟研究
|
摘要
运用三维弹性有限元数值模拟方法对南水北调西线工程区断裂位移随深度变化进行了研究,通过模拟不同宽度断层的位移随深度变化、计算不同断层弹性模量下断层位移随深度变化及计算1000m深度以内水平位移、垂直位移相对于地表的增加比例,得出了在1000m埋深内断层水平位移和垂直位移增加比例随深度变化的关系曲线。试验表明,在埋深1000m内,断层水平位移增加比例小于垂直位移增加比例;在其他参数固定的情况下,采用不同的震源破裂长度计算断层滑距随深度增加的比例相同。该工作可为工程设计提供依据。
3D elastic finite element method is used to study the fracture displacement of site in the west route of the South-to-North Water Transfer Project.By simulating the displacements of faults with different widths and elastic moduli,it is showed that the horizontal fault displacement's rising rate is smaller than that of the vertical fault at 1 000 m under the ground.Keeping the other parameters constant,the rising rate of the fault slipping displacement is the same as the calculated value using different epicenter fracture lengths.The study of the present work can be a good reference to the engineering practice.
