Abstract

F₅₃ fault alteration and fractured belt located in the left dam- abutment of a hydropower station is the main engineering geological problem of the project. Engineering geological properties of F₅₃ fault alteration are analyzed in detail, combing with geological phenomena and test data. With the X ray diffraction analysis, the main mineral component of the fractured rock is identified. Based on the conventional triaxial compression testes, the stress-strain characteristic of F₅₃ fault material is examined. In conjunction with site specific analyses, the pre-existing state of rock mass in F₅₃ fault is expounded, which can offer reliable evidence to constructions of projects.
