| 摘 要： | 本文对国内外岩体工程反分析技术的兴起及发展作了阐述，并指出其存在的问题，特别是确定性反分析所受的局限性。围岩体的变形及各物理力学参数随开挖的变化是处于一种随机动态过程，应采用非确定性方法来探究。对此，本文提出扩张卡尔曼滤波器与有限元分析耦合法是解决此问题的较好方法，并开发出实用计算程序。

| Abstract: | The rise and development of counter - analysis technique for rock engi-neering both abroad and at home were described. Its problems were pointed out, especiallyits limitation in definite counter analysis. The deformation and physico - mechanical pa-rameters of rockmass is in a state of random dynamic process with change of excavation, soit should be investigated by indefinite method. In this paper and expanding Kalman fillercoupling with finite element analysis was suggested as a better method for solving thisproblem and a practical computer program was developed. |
