摘要
广州市黄沙南站某住宅楼工程临近地铁线路,周边环境复杂,管线较多,场地狭窄。工程整体采用地下连续墙内支撑支护。考虑到对地铁隧道的保护,在临近地铁线路条件下基坑设计和施工过程中,采取了调整地铁侧地下连续墙的厚度、合理安排槽段开挖顺序、使用旋喷桩和水泥搅拌桩处理、按一定的原则开挖土方、控制支撑的施工,以及采取相应的止水降水等措施。监测结果表明,效果显著。
A residence in Guangzhou Huangsha south station is near the subway line, with complex surrounding environment, dense pipelines and limited site. Internal support of diaphragm wall is used in whole project. Considering of protecting the rail, some new treatment methods in the design and con- struction of foundation are proposed, such as adjusting the thickness of the diaphragm in the side of the subway, arranging a reasonable excavation sequence of slot section, treating with the diaphragm using jet grouting pile and cement mixing construction of the support, and pile, taking excavating earth according to a certain principle, controlling the corresponding measures for stopping and precipitating water. Ac- cording to testing results, the effect is remarkable
