采空区变形对渠体影响分析

Impact Analysis of Channel Configuration in mined-out Area

本文介绍了南水北调工程所通过的焦作煤矿开采区基本情况.根据采空区地表移动与变形的特征,本文重点分析了地表下沉、倾斜变形、水平变形与曲率对渠体的不良影响,提出了采空区渠体稳定性验算的计算方法及其计算公式。

This paper briefly introduces the basic situation of Jisozuo coal mining of middle segment of water transfer engineering from southern to northern. According to the characteristic of the surface migrating and deforming in mined-out area, This paper mainly analyaes the adverse effects of ground surface subsidence ,inclination deformation.horizontal deformation and angularity on channel configuration ,and puts forward computing methods and computing formulaa on stability of channel configuration in mined-out axea.
