摘要
黄登水电站地下厂房洞室群主要由主副厂房、主变室、母线洞以及进厂交通、通风排风等辅助洞室组成,整个厂区洞室纵横交错规模宏大,属大型地下洞室群,其围岩支护参数应根据围岩稳定分析及施工期反馈分析成果进行动态调整。监测成果表明黄登地下厂房洞室群的开挖方式及围岩支护参数是合理可靠的,黄登地下厂房洞室群围岩在系统支护及局部加强支护联合作用下整体处于稳定状态。
The underground powerhouse cavern group of Huangdeng Hydropower Station is mainly composed of main and auxiliary powerhouse, main transformer room, bus tunnel, incoming traffic, ventilation and air exhaust and other auxiliary caverns. The caverns of the whole plant area crisscross in a large scale and belong to large-scale underground cavern group. The surrounding rock support parameters shall be dynamically adjusted according to the results of surrounding rock stability analysis and feedback analysis during construction. The monitoring results show that the excavation method and surrounding rock support parameters of the cavern group of Huangdeng underground powerhouse are reasonable and reliable, and the surrounding rock of the cavern group of huangdeng underground powerhouse is generally stable under the combined action of systematic support and local strengthening support.
