软弱围岩物理力学指标的统计分析

The Statistical Analysis of the Physical and Mechanical Parameters of Soft Rock Mass

运用概率统计原理,对浅埋地下结构软弱围岩物理力学指标的实测数据进行统计分析,从而求得各有关随机变量的概率统计特征。所得结果可为今后《铁路隧道设计规范》改革和类似地下结构的可靠度分析提供重要参考。

By using the probability statistical principle,the data of the physical and mechanical parameters of soft rock mass around shallow-buried underground structures are analyzed. Thus their statistical characteristics of random variables are found out. The results obtained can be provided for reference in the revision of design standards for railway tunnels and in the reliability analysis of similar underground structures.
