复杂溶岩地质钻孔灌注桩施工技术研究

Research on Construction Technology of Bored Pile in Complex Karst Geology

结合某地理位置位于喀斯特地形地貌的工程项目,针对施工钻孔灌注桩过程中遇到的溶洞状态不一、大小不同、形态各异等问题,详细介绍和总结了多种桩基施工工艺和桩基遇溶洞时的处理方法。经过实践得出结论:在施工过程中遇到溶洞时,首先需要了解溶洞的位置、大小等信息,然后根据具体情况选择合适的处理方案,以此保证施工质量和安全。

Combined with the engineering project located in karst topography and geomorphology,in view ofthe problems of different states,different sizes and morphologies encountered in the construction of bored piles,a variety of pile foundation construction techniques and treatment methods when pile foundations encounter karst caves are introduced and summarized in detail.After practice,it is concluded that when encountering a cave during the construction process,it is first necessary to understand the location,size and other information of the cave,and then choose the appropriate treatment plan according to the specific situation to ensure the quality and safety of construction.
