摘要
Abstract
Semi-deterministic block in a cavern is composed by the deterministic and random structure surfaces (matrix fracture) in a rock mass. The semi-deterministic blocks usually show zonal or centralized distribution along the deterministic structure surface and the intersections between the deterministic structure surfaces,and their sizes are very random. Little attention has been paid to these blocks;however, the stability of the blocks is crucial to the construction safety. The semi-deterministic blocks in the factory building of a hydropower station are investigated in this paper, including the analysis of the possibility for the formation of the semi-deterministic blocks based on the structure surfaces at all levels and the stability of the blocks once they develop. The SASW program is used to calculate the stability factors of the blocks,and this program is developed by Chengdu U-niversity of Technology and based on the vector calculation method. The stability of the semi-deterministic blocks in the cavern has been preliminarily studied, which can be beneficial to the knowledge of the construction safety in these blocks.关键词
