摘要
为了给水库大坝的除险加固工作提供依据,需要确定大坝渗漏原因,明确可能存在的渗漏通道。本研究通过综合地质勘察,利用地质测绘、勘探、物探、室内与现场试验等手段,深入探究坝址区喀斯特发育情况,最终确定覆盖层产生管涌、流土破坏进而导致渗漏,基岩存在的喀斯特及架空通道导致塌陷。
In order to provide basis lor reinforcement work ol dam, it is necessary to determine the cause ol dam leakage and identify the possible leakage channels. Through comprehensive geological investigation in this study, geological sur-vey , exploration,geophysical exploration,indoor and field tests are carried out to explore the development ol Karst in dam site area, linally,the reasons ol piping, llowing soil damage, the existence ol bedrock Karst and collapse ol aerial channels are determined.
