摘　　要：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。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.
