桩基是桥梁结构最为常用的一种基础形式,其施工质量的好坏直接影响了整个桥梁工程的质量。同时,桩基能够穿过溶洞,起到减少基础沉降与结构变形的作用。基于此,对溶洞群地区桥梁桩基设计、施工问题及其应对策略进行探讨,有着非常重要的意义。本文先具体对溶洞地区桥梁桩基设计进行分析,然后再在此基础上以某桥梁工程为例来对其施工问题及其应对策略进行具体阐述,以此采为业内人士提供相关的参考。 Pile foundation is the most commonly used form of bridge structure, whose quality of construction directly affects the quality of the whole bridge project. At the same time, the pile foundation can penetrate the cave and play the role of reducing the foundation settlement and structural deformation. Based on this, it is of great significance to discuss the design and construction of bridge pile foundation in the cave area and its coping strategies. This paper first concretely analyzes the design of bridge pile foundation in the cave area, and then on this basis, taking a bridge project as an example to concretely explain its construction problems and its coping strategies, so as to provide reference for people in the industry.
