摘要
阐述了软弱岩体内开挖大型硐室过程中，围岩的变形特征及其规律，根据位移速度和最大位移量的极限值，成功地进行了监测预报，取得了满意的结果。对矿山地下工程有一定的指导意义。
The charactery and regularty of surrounding rock deformation of large cave in soft rock are expounded in this paper.According to the displacement rate and limited displacement,deformating and forecasting have been achieved.It will be certain current significance to underground mine engineer.
