摘要
南京地铁奥体中心站深基坑工程采用土钉墙支护方案,对土钉墙支护施工的监测结果分析表明,这种围护形式施工环境较好,施工速度快;但在软弱土层中采用尤其要重视“时空效应”,且基坑边坡的位移及周边的沉降较大。
Soil-nail wall support was employed in the deep foundation works of Olympic Sports Center Station of Nanjing Metro Project. Analysis on the monitoring result of the soil-nail wall construction demonstrates that this form of support creates good construction environment and fast construction speed. However, when it is used in soft soil, particular attention should be paid to ＂time-space effect＂ and foundation pit will have big slope displacement and boundary settlement.
