一、前言鲁布革水电站地下厂房的大型洞室群,全部采用锚喷作为永久支护,需要及时地对施工期和运行期的围岩稳定和支护效果作出正确的评价。以往由于理论计算和模拟试验判断围岩稳定性难以充分反映地质状况和边界条件的复杂性,致使计算成果与实际情况差异较大。为了积累高边墙大跨度地下厂房设计与施工的经验,鲁布革地下厂房布置了一套完整的监测系统,
I. Introduction The large caverns in the underground powerhouse of the Lubuge Hydropower Station are all anchored and sprayed as permanent supports. The correct evaluation of surrounding rock stability and support effect during construction and operation is required. In the past, it was difficult to fully reflect the geological conditions and the complexity of the boundary conditions by judging the stability of the surrounding rock by theoretical calculation and simulation tests, resulting in large differences between the calculated results and the actual conditions. In order to accumulate experience in the design and construction of high-rise long-span underground powerhouse, a complete set of monitoring system was arranged in the underground factory building of Lubuge.
