温峡口水库位于湖北省钟祥县境内,是一座以灌溉为主的综合利用的大型水库工程。水库于一九六六年九月兴建,一九六九年基本完工。枢纽地质复杂,工程全部座落在断层破碎带上,横穿底孔的断裂结构有三条较大断层,将岩石切割得十分破碎。底孔全长284米,由45米园形斜洞与239米平洞组成。斜洞直径2.5米,平洞高3米,宽2.5米。由于地质条件复杂,岩性变化大,物理力学性能差异显著,加上施工期间受地下水影响
Wenxiakou Reservoir is located in Zhongxiang County, Hubei Province. It is a large-scale reservoir project with comprehensive utilization mainly of irrigation. The reservoir was built in September 1966 and basically completed in 1969. Complex geological hub, the project are all located in the fault zone, the fracture structure across the bottom hole has three major faults, the rock is very fragmented. Bottom hole length of 284 meters, 45 meters from the garden-shaped inclined hole and 239-meter-hole composition. Diagonal hole diameter of 2.5 meters, flat hole 3 meters high and 2.5 meters wide. Due to the complex geological conditions, large changes in lithology, significant differences in physical and mechanical properties, coupled with the impact of groundwater during construction
