反分析垮山力学参数静不定问题的解决方法

Solution to Static Undetermination Problem in Deriving the Mechanical Parameters of Hill Collapse by Counteranalysis

应用工程反分析求取垮山过程的岩体力学参数时，由于静不定现象得不到唯一解。本文提出的数理统计学的优化法圆满地解决了这一难题，并成功地应用于石人嶂钨矿莲花山垮山预报，避免了一次重大灾害事故。

In deriving the mechanical parameters of rock mass in hill collapse process by applying the engineering counteranalysis method,the only solution couldn't be obtained because of the static undetermination phenomenon.This difficult problem has been satisfactorily solved by the optimization method of mathematical statistics that was suggested by the authors .Its successful application in predicting lianhua hill collapse in Shirenzhang Wolfram Mine has avoided a great disaster.
