【摘要】 采空区架空送电线路岩土工程勘测历来是电力勘测的难点 ,尤其是急倾斜厚煤层采空区更需慎重对待。某 50 0kV架空送电线路S号塔 ,由于距离较远的采空区塌陷导致地表引张变形而引起塔基裂缝 ,塔材变形。对塔基稳定性进行评价 ,提出处理方案。更多还原

【Abstract】 磆e geotechnical survey of power transmission line on the mined-out area has been important and difficult for the power project,more attention must be paid to those of the sharp dip angle coal layer In this paper it is described that the tower № S in a certain 500kV power transmission line,which was far away from the coal mine,was deformed by the fracturing,following the ground tension deformation caused by the subsidence of the minde-out area The author evaluates the stability of the tower foundation and presents the treatment methods更多还原
