摘　　要：超深基坑安全与施工进度息息相关,土方开挖与转运速度是基坑施工进度的重要影响因素。苏州中南中心项目利用前期工程试桩、试验锚桩及一柱一桩永临结合作为临时运输坡道竖向支撑,节约深基坑土方开挖过程中转土、吊土时间,有效加快施工进度,确保基坑安全,同时节约成本,取得良好综合效益。The safety of ultra-deep foundation pits is closely related to the construction progress.The speed of earthwork excavation and transfer is an important factor affecting the construction progress of foundation pits.The Suzhou Zhongnan Center project uses the pre-engineering test piles,test anchor piles and a pile-by-pile permanent combination as the vertical support of the temporary transport ramp,saving the time for soil transfer and lifting during the excavation of the deep foundation pit,and effectively speeding up the construction progress.Ensure the safety of the foundation pit,while saving costs and achieving good comprehensive benefits.
