| 摘 要： | 岩溶地质对地铁盾构隧道、明挖结构的施工以及建成后运营的维护都有较大影响。广州地区地铁施工在岩溶地质条件下，根据地质情况划分高、低风险区，高风险区范围岩溶、土洞必须进行填充处理。以广州地铁三号线北延段的岩溶处理设计为例，根据具体工程地质及水文地质资料，详细介绍岩溶处理的目的、原则、措施、施工注意事项及检测标准等内容。岩溶处理具体措施分盾构区间地段和明挖结构地段2类。

| Abstract: | Karst geology has great influence on the construction and operational maintenance of shield-bored Metro tunnels and cut-and-cover structures.The karst geological conditions encountered in Guangzhou Metro construction can be divided into high risk area and low risk area.The karst carve in high risk area must be filled up.Taking the design of the karst treatment of the north extension section of No.3 line of Guangzhou Metro as an example,the author presents the treatment intention,treatment principle,treatmen... |
