钟祥市双河镇斑竹村岩溶地面塌陷灌浆治理效果分析

摘要

According to the features of subsidence area structure of karst ground ,karst cave, development grades of chan-nel and high solubility , using pressure grouting reinforcement means to govern .Karst cave grouting filling can block the karst waterrunning channel , weaken the carbonate dissolution phenomenon , improve the stability of surface rock .From the monitoring results of view , treatment effecthe method oft is good .It achieves good economic and social benefits .%针对钟祥市双河镇斑竹村岩溶地面塌陷区构造、岩溶洞穴、管道发育，岩石可溶性强等特征，采用压力灌浆加固手段实施治理。对溶洞实行灌浆充填，阻断岩溶水运行通道，消弱碳酸盐岩溶蚀现象的发生，提高了地表岩体稳定性。从监测效果看，该方法治理效果好，区内各项设施运转顺畅，取得了良好的经济与社会效益。
