Abstract: In order to reflect the influence of complex geologic faults in large underground chamber, the authors put forward a numerical simulation and analysis method for the connotative fault element. The method establishes an equivalent element comprising both rock material and fault material, which can decrease the influence of faults incision. By this way, not only the mesh generation of large underground chambers becomes relatively convenient and feasible, but also the influence of complex geologic faults on stability of surrounding rocks is reflected effectively. At last, a sample about underground chamber of Three Gorges Project is given, which testifies that the method is reasonable and provides an effective computation method and train of thought for the analysis of complex geologic faults structure.

Key words: complex geology, connotative fault, numerical analysis
