pressure of surrounding rock

In this paper, a temperature stress integral formula for the linings and surrounding rock of hydraulic pressure tunnels has been developed accurately by the elastic-contact theory on the basis of mechanics of elasticity.

本文还应用弹性力学中的弹性接触理论，严密地导得了水工有压隧洞衬砌和围岩的温度应力积分表达式。

The preliminary study to the characteristics of surrounding rock and support design procedures in working faces of strong roof and high ground pressure of deep mines are conducted in this paper using several important methods such as numerical simulation, theory analysis and measuring data analysis from locales.

本文采用数值模拟分析、理论分析和现场实测数据分析等研究方法，对深井高地压坚硬顶板采场围岩特性与支护设计进行了初步的研究。

The Test Study of the Surrounding Rock Pressure Acting on the Composite Lining in Weak Rock of Nanling Double Track Railway Tunnel

南岭双线铁路隧道软岩复合式衬砌围岩压力的试验研究

By means of numerical simulation and in-situ test, this article research on distribution rule of surrounding rock pressure and contact pressure and safety evaluation and design optimization of secondary linings.

本文通过现场试验并结合数值模拟研究的方法，对围岩压力和接触压力的分布规律以及二次衬砌安全性评价和优化设计作了初探。

The deformation of surrounding rock appears mainly in abutment pressure influence zone. Reasonable roadway supporting should control the deformation of surrounding rock in intense stage of mining influence. Supporting design ideas of tailentry and head entry should be changed from the loading control to the deformation control.

围岩变形主要发生支承压力影响区，合理的巷道支护应能控制采动影响剧烈阶段的围岩变形，顺槽支护设计理念应从载荷控制向变形控制转变。
