摘要 凤-同区间是广州市轨道交通二、八号线延长线关键控制工程之一,采用矿山法施工。地质条件十分复杂,周边沿线桥梁密布,需要采用桩基托换。古建筑林立,严重影响施工进度和作业安全。文章从工程地质、设计及施工角度对其重难点进行了梳理,研究成果可为工程提供技术支持,也可为类似工程提供参考。 Fengtong-Tongtong section is one of the key control projects of the extension line of Guangzhou Metro Line 2 and 8,which is constructed by mining method.Geological conditions are very complex,and the surrounding bridges are densely distributed,so pile foundation underpinning is needed.Ancient buildings stand in great numbers,which seriously affects the construction progress and operation safety.In this paper,the key and difficult points of Engineering geology,design and construction were sorted out. The research results can provide technical support for the project,and also provide reference for similar projects.
