【摘要】 针对地下工程顶部层状砂岩中存在顺层发育软弱夹层的情况,分别对开挖后可能出现的层间滑动破坏范围、岩板的沉降、折断和临界长度进行计算,并分析其稳定性,提出了根据砂岩沉降位移评价岩体强度参数的思路和方法更多还原

【Abstract】 Based on the bedding features of weak intercalations in sandstone plates near the top of an underground cavity, the probable failure scale of bedding sliding, the probable settlement, the folding places and the critical length of sandstone beams are computed separately, and the stability of underground cavity is analysed. This paper points out that the rockmass strength parameters can be evaluated according to the settlement of rock plotes.更多还原
