摘要
福宜项目万溪冲特大桥岩溶发育,存在不同高度、不同填充类型的单个或串珠型溶洞,且溶洞之间存在连通现象.本文从勘察方法、钻机选择、溶洞处理方法三方面在设计角度及施工角度分别阐述了岩溶发育段桥梁桩基质量控制.
Karst is developed in Wanxichong Bridge of Fuyi Project, with different heights, different filling types of single or beaded caverns, and there is a connection between them. This paper expounded respectively the quality control of bridge pile foundation in karst development section from the aspects of surveying method, drilling rig selection and treatment methods of karst cave in design and construction.
