摘要：
以南宁轨道交通1号线火车站站有旧锚索的地下连续墙为例，通过经济、安全等方面对比分析，采用方案比选方法确定了连续墙界限内锚索处理推荐方案。对锚索破断强度、锚索与地层之间锚固力、槽壁机抓斗提升力进行理论计算分析和处理旧锚索时连续墙槽壁稳定性的分析，论证了推荐方案的可行性； 并通过实际施作和基坑开挖后的验证，对槽壁机抓切连续墙界限内锚索进行了验证。

Abstract:
In this paper, comparison and contrast is made among old anchor bolts clearing programs of underground diaphragm wall of Nanning Railway Station station of Nanning railway transit in terms of economy and safety. Theoretical calculation is made on cutting strength, anchoring force between anchor bolt and soil and hoisting force of slot machine, and the stability of underground diaphragm wall is analyzed. In the end, the rationality of the using of slot machine is testified.
Key words: Nanning railway transit, foundation pit, old anchor bolt, clearing
