| 摘 要： | 对珠三角城际快速轨道交通广佛线西朗地铁站的基坑支护结构进行设计优化,采用疏排钻孔灌注桩替代密排人工挖孔桩,并对支护体系的间距进行调整。通过对支护结构的设计验算以及现场施工过程的监测表明,该设计优化方案大幅减少了桩基成孔、钢筋制安、混凝土浇筑等工程量,节约了工期,同时为基坑土石方开挖和主体结构施工创造了较为便利的施工条件。

| Abstract: | For the optimal design of the supporting structure for the foundation pit in Xilang Subway Station on the Guangzhou-Foshan express rail transit, sparse bored piles were used instead of close artificial dig-hole piles and the spacing of the support system was adjusted. The calculation of the supporting structure and field monitoring of the construction process show that this design optimization scheme has significantly reduced the workload including boring for pile foundation, steel bar making and installation and concrete placement, saved much time and created more convenient conditions for foundation pit excavation and main structure construction . |
