摘要
钟祥市斑竹垱岩溶地面塌陷是典型的采矿降水疏干影响区地面塌陷。该岩溶地面塌陷的形成与岩溶发育程度、水文地质条件、人类工程活动密切相关,构造破碎带(断裂)促使地下水富集带发育岩溶,岩溶管道和溶洞为塌陷提供空间条件,采矿降水改变疏干区地下水径流途径诱发塌陷形成。采用注浆加固、回填、河床整治、绿化等工程对斑竹垱岩溶地面塌陷区进行综合治理,取得预期建设效果。
Banzhudang karst ground collapse in Zhongxiang City is a typical ground collapse in the affected area of mining precipitation.The formation of the karst ground collapse is closely related to the degree of karst development,hydrogeological conditions and human engineering activities.Structural fracture(fracture)promotes the development of karst in groundwater enrichment zone.Karst pipelines and karst caves provide space conditions for the collapse.Mining precipitation changes the groundwater runoff in the sparse area to induce collapse.The grouting reinforcement,river bed improvement,greening and other projects are used to comprehensively treat Banzhudang karst ground subsidence area,and the expected construction effect is achieved.
