摘　　要：现场量测位移的分析法是通过测量开挖硐室、隧道、井巷等地下工程的周边和围岩内的相对位移和绝对位移值来反推岩体的原始地应力场及岩体力学参数。利用线弹性有限元位移反分析程序计算出某石棉矿区的初始地应力场值,并得出较大的水平应力,这正是该矿地压严重显现原因之一。Back analysis of measuring displacements on the spot is an advanced method applied to get the original esrth stress field and rock mechanic parameters by measuring relative of(and)absolute displacements in wall rocks of chambers,tunnel levels etc. during excavation. Linear -elastic FEM back analysis was made use of calculating the original rock stress value and bigger horizontal stress value of an asbestos deposit. The authors believed that the bigger horizontal stress value was one of reasons causing serious mining subsidence in this ore district.
