The fracture of rock mass for main transformer chamber in HuangGou hydropower station is
very developed. The blocks slide along the discontinuous face or free face with the excavation of cavern. It
leads to the failure of normal construction. In the study, according to geology of disclosed discontinuous
face in detecting cavern and local three-dimensional coordinate of underground caverns, the vector analysis
program for tunnel stability VATS is compiled by using the method of vector analysis of the block theory
which is applicable to analyze the discontinuous rock mass and numerical software MATLAB. The
occurrence of joints, the coordinate of measuring point, the radius and vertical wall height of underground
caverns and other relevant engineering datum is required to input the program. The combination of
discontinuous face, boundary condition, geometric parameter, the mode of failure and stability factor of
existent unstable blocks is obtained. The geometry distributing characteristic of block and key
discontinuous faces in different position is figured by the AUTOCAD software. The guidance for
construction of underground caverns is provided.
Key words: Block , key discontinuous face, main transformer chamber, the distributing characteristic, vector analysis for tunnel stability, ,
