| 摘 要： | 对于软弱破碎岩体,在埋深较浅的情况下,可以采用太沙基理论计算围岩压力。破裂面两侧作用着摩擦力,采用统一强度理论考虑破裂面两侧的摩擦力,从应力传递概念出发,推得了作用于衬砌上的垂直围岩压力公式。计算结果表明强度理论的效应是明显的。本文给出了围岩压力的范围值。

| Abstract: | pressure of surroungding rock mass for flabby fracture rock mass can be calculated by K. Terzaghi theory in case of covered up fleet. using the unified strength theory, taking fiction which acted at the two fracture sides into account, starting off stress transfer concept, this article deduced the formulas of vertical pressure of surroungding rock mass which acted at the liner. the calculation result indicated that the strength theory effect is obvious. this article provided the range of pressure of surroungding rock mass. |
