桥梁桩基施工溶洞的处理方法

Bridge Pile Foundation Construction Karst Cave Treatment Method

以广西某工程为实例,基于工程难点,对岩溶地区钻孔灌注桩的溶洞处理方法以及原理进行了具体的分析,介绍了不同孔径对应选择的溶洞处理方法,经过实践证明取得了满意的效果,有效节省了钻孔桩施工工期。

Taking a project in Guangxi as an example, based on the engineering difficulties, this paper analyzes the karst cave treatment methods and principles of cast-in-place bored piles in karst area, introduces the corresponding treatment methods of karst caves with different pore diameters. Through practice, it has been proved that satisfactory results have been achieved and the construction period of bored piles has been effectively saved.
