大跨度高边墙地下洞室围岩压力研究

Analysis of Rock Pressure for Large Span and High Side-wall Underground Cavern

作用于地下洞室衬砌结构上的围岩压力的计算方法有多种,采用多种围岩压力计算方法计算某大跨度、高边墙地下洞室的围岩压力并结合施工监控量测进行对比分析,以提出针对硬岩地层中开挖的大跨度、高边墙深埋洞室围岩压力计算的合理方法。

Different calculation methods of rock pressure are compared with the monitoring and measuring results of an engineering case. It aims to summarize a proper calculation method of rock pressure for large span and high side-wall cavern excavated in the hard surrounding rocks.
