摘要
以广东省某高速公路岩溶区的一座双柱式墩为例,介绍了该墩桩基的溶洞处治方案、桩基的设计思路,并依据相关规范对该墩桩基进行验算,同时对桩端岩溶顶板的稳定性进行了分析和计算,其方法和结论可为同类桥梁桩基设计提供参考和借鉴。
Taking a double column pier of highway in karst area of Guangdong province as an example,this paper introduced the karst cave treatment scheme and the design ideas of pile foundation. According to the relevant specifications, it also checked the pile foundation, analyzed and calculated the stability of karst roof at the end of pile. The methods and conclusions could provide reference for the similar bridge pile foundation design.
