摘要
1990年6月一场暴雨后,涟源钢铁厂铁路路基塌陷约3600m^2。从区内的水文地质、工程地质条件分析,引起塌陷的原因主要是由毛细水作用、真空吸蚀作用、地表水作用、地下水的潜蚀作用和震动作用的踪合影响,从而提出防治再次塌陷的方案,宜采用桥托、注浆、钻孔通气、疏排地表水等措施。
A railway-bed subsidence of about 3600 m^2 in Lianyuan steelworks occurred after a storm in June, 1990. Analysed from the hydrogeologic and engineering geologic conditions of the area, the cause led to subsidence lies mainly in the synthetical influence of capillary water, vaccum attraction and surface water erosion as well as the underground corrosionand quaking of underground water. Therefore a scheme for its prevention and control is put forward. It is suitable to take the measures such as bridge support, mortar injection, ventilation through drilling, and dredge and drainage of surface water.
