摘要
为了避免喀斯特塌陷对孙祖河橡胶坝工程项目实施造成威胁,通过野外调查、工程地质测绘、钻探、现场试验、稳定性分析等手段,系统分析研究区喀斯特塌陷的特征,探讨喀斯特塌陷的成因演化机制,查明喀斯特塌陷的诱发因素,并对研究区喀斯特塌陷的稳定性及其演化趋势进行预测.结果表明,研究区目前处于土洞形成阶段,外界水动力条件的改变是研究区喀斯特塌陷稳定性的主要影响因素,具备进一步发展形成喀斯特塌陷的空间条件、物质条件和水动力条件,在进行地下水开采时应控制地下水位最大降深.
Abstract
To avoid threat of karst collapse to implementation of the Sunzu River rubber dam project,characteristics of karst collapse in the research area were systematically analyzed by means of field survey,engineering geological mapping,drilling,field test,and stability analysis,so as to explore genetic evolution mechanism of karst collapse and identify inducing factors of karst collapse.Stability and evolution trend of karst collapse in the research area were predicted.The results show that the research area is in the stage of soil cave formation at present,and the change of external hydrody-namic conditions is the main influencing factor of the stability of karst collapse in the research area.There are space,material,and hydrodynamic conditions for further development of karst ground collapses,and the maximum groundwater level depth should be controlled during groundwater exploitation.
