摘要

Finite Element Method is commonly used in geophysical numerical simulation. According to rock geophysical characteristics of the west route of South-to-North Water Diversion project, different 3-D models were constructed and numerical calculation analysis was carried out with finite element method. The pattern of the field in three-dimensional space is simulated, the characteristics of different abnormal geologic bodies were probed. It has established a basis for improving CSAMT accuracy of surveying the abnormal geology body hidden in deeply buried tunnel in South-to-North water diversion west line project.
