摘要
通过广东清远北江四桥工程实例,提出复杂岩溶地区的桥梁桩基设计思路,结合不同施工环境分析三种不同形式的溶洞桩基,保证复杂岩溶地区桥梁桩基设计满足其承载能力要求,同时针对不同的地质条件提出桩基关键技术施工措施,为类似工程设计和施工提供了参考借鉴。
Taking Qingyuan North River Bridge IV in Guangdong as an example, the article puts forward the design concept of bridge pile foundation in the complex karst area, and analyzes three different karst cave pile foundations in the different construction environments, which guarantees the design of bridge pile foundation in the complex karst area to satisfy its bearing capacity requirements. Aiming at the different geological conditions, the article puts forward the key technological construction measures of pile foundation in order to provide the reference for the design and construction of the similar projects.
