应用岩体经验强度准则确定圆形竖井极限深度
Determination of Limit Depth of Circular Shaft Using Rockmass Empirical Strength Rule
【摘要】 根据岩体的强度特性确定圆形竖井极限开挖深度是非常重要的。本文简单介绍了竖井围岩应力的计算方法 ,基于经验强度准则对岩体破坏的描述 ,推导出竖井极限深度的计算公式
【Abstract】 It is very important to determine the limit excavation depth of a circular shaft according to the strength characteristics of rockmass. This paper describes the calculation method of wall rock stress of a shaft. Based on the rule of empirical strength, rock failure is described and the calculation method for shaft limit excavation depth is deduced.
