“旺采”条件下地表沉陷预测方法

Prediction methods of surface subsidence under the condition of Wongawilli mining method

提出依托FLAC^(3D)数值模拟技术嵌入改进后的概率积分法计算程序这种新的计算体系来研究地表沉陷。通过工程验证,新的计算体系不但节省监测费用而且能够适应不同工程地质条件下的分析计算,比单纯使用概率积分法或者数值模拟技术等更有实际意义。

The article presents the probability integral method after FLAC^（3D） numerical simulation technology embedded improvement to calculate procedure to research surface subsidence. Through the engineering verification, this new calculation system can save monitoring fees and be adapt to the analysis and calculation of different engineering geological conditions, Which is more practical than the pure probability integral method or numerical simulation technology.
