厚松散层地表移动变形预计的双曲函数法

Applying hyperbolic function to predict the surface movement and deformation in the condition of thick alluvium

在厚冲积层条件下, 根据上覆岩层不同的介质特点, 通过理论分析, 采用地表移动变形计算的双曲函数法进行预计, 并对预计结果与实测数据进行了对比, 在预计参数选取比较准确的情况下, 预计结果是令人满意的, 解决了概率积分法在预计厚松散层开采条件下盆地边缘偏差较大的问题。

According to the different properties of rock strata under thick alluvium, the model of hyperbolic function is introduced to predict the surface subsidence through theory analysis. And the prediction data were compared with the actual observation data. It was concluded that the prediction solution is satisfied, if the prediction parameters were exactly selected. Using the method of hyperbolic function to predict basin fringe, it solved the problem that the deviation is greater.
