摘要
地下开采所引起的地表任意点下沉，通常是以走向和倾向断面下沉函数的乘积表示。这一方法实质上假定走向、倾向断面为互不相关的主断面。采用剖面函数相关概念，分析了几何、物理条件对下沉盆地主断面方向的影响，并对相关系数和主断面参数的确定作了讨论，同时给出了实例计算结果。
In order to predict mining subsidence behaviours of the surface in extracted area, the movement of any point is often expressed by multiplication of two main profile functions. This method supposes the two profile functions are independent from each other. In this paper, the relativity of subsidence functions, which is caused by geometric and physical conditions, is introduced. The authors derived the equations associated with the relative parameter and provided a new basis for prediction of subsidence. They illustrated the accuracy of prediction of subsidence by the new method.
