摘　　要：以柳州双拥大桥为依托,对岩溶地区重力式锚碇设计进行了探讨。从结构形式优化、基坑支护与止水、基底加强处理、主要结构分析等几方面进行了详细阐述。采用的锚碇设计方法较好地解决了岩溶地区锚碇开挖、止水以及基底承载力不足等问题,可为类似工程提供参考。Based on the Shuangyong lSridge in Liuzhou, gravity anchorage design in karst area is discussed. Detailed elaborations are made in the paper from aspects of optimization of the structure forms, retaining for and protection of foundation excavation, base treatment and structure analysis. Anchorage design method which has been adopted solves several problems such as foundation excavation in karst Region, sealing and insufficient bearing capacity and so on, which can provide reference for similar projects.
