摘　　要：针对岩溶山区的复杂多变的工程地质条件进行分析,并与其他地质条件下的基桩施工相比,岩溶地区基桩施工非常困难,且容易出现质量缺陷。文中通过介绍岩溶山区基桩常用的施工方法和检测方法,结合岩溶地区实际工程案例,分析该工程基桩缺陷问题,并提出相应防治措施,对处理后的缺陷基桩进行检测发现处理效果良好。The complex and changeable engineering geological conditions in karst mountainous areas were analyzed. Compared with the construction of foundation piles under other geological conditions, the construction of foundation piles in karst areas is very difficult accompanying with quality defects. This article introduces the commonly used construction methods and detection methods of foundation piles in karst mountainous areas, and the actual engineering cases in karst areas were analyzed. Engineering foundation pile defects, and corresponding prevention measures were proposed. The defective foundation piles after treatment were inspected with good treatment effect.
