深部坑道围岩压力与变形分析

随着地下空间开发不断向深部发展，出现了用连续介质理论无法解释的现象。以普氏理论为突破口，通过实例分析，从定量的角度出发，找出了普氏压力计算存在的不足，而采用强度理论得出的结果符合实际的物理力学理论。同时也指出，在连续介质理论框架内该强度理论也有其不足，主要在于没有考虑“隐形”区域，暗示为了更精确地描述岩石压力，必须采用新途径。

Analysis of pressure and deformation of wall rock near deep tunnel

Along with the exploitation of the underground space approaches to the deep constantly, some phenomenon cannot be fully explained by mechanics of continuous media. The Protojiakonov’s Theory as a breakthrough, the shortage of the pressure calculation is found out from quantitative angle by analyzing example. The result from strength theory is in tally with the actual physico-mechanical truth. The shortage of strength theory is shown that in the continuity theory-frame also; mainly because the invisible district wasn’t considered. The new methods must be adopted in order to describe the rock-pressure accurately.
