高速公路桥梁溶洞桩基施工技术

Construction Technology of Pile Foundation in Karst Cave of Expressway Bridge

由于溶洞地区地质复杂,难以彻底了解洞内情况,因此在溶洞地区进行高速公路桥梁桩基施工具有一定的挑战性。结合具体的工程实例,介绍了岩溶地质条件下桩基施工的工艺流程,并对工程中出现的问题提出有效的解决措施,为同类工程提供借鉴。

Due to the complexity of geology in karst cave, it is difficult to thoroughly understand the situa-tion of the karst cave, and therefore it is challenging for construction of expressway bridge pile foundation in karst area. Combined with one engineering example, this paper introduces the process of pile founda-tion construction in karst geological conditions, and puts forward effective measures to solve the problems in engineering, in order to provide reference for similar engineering.
