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。
對珠三角城際快速軌道交通廣彿線西朗地鐵站的基坑支護結構進行設計優化,採用疏排鑽孔灌註樁替代密排人工挖孔樁,併對支護體繫的間距進行調整。通過對支護結構的設計驗算以及現場施工過程的鑑測錶明,該設計優化方案大幅減少瞭樁基成孔、鋼觔製安、混凝土澆築等工程量,節約瞭工期,同時為基坑土石方開挖和主體結構施工創造瞭較為便利的施工條件。

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 ar-tificial dig-hole piles and the spacing of the support system was adjusted .The calculation of the sup-porting 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 .
