摘　　要：超厚高透水性砂层城市深基坑施工与一般的基坑施工存在差异,本文主要以实际基坑施工工程项目为例,利用无止水帷幕深基坑降水施工技术开展施工,同时对基坑施工技术和抗浮施工技术进行了分析,探究了一种缩短工期且降低施工成本的施工工艺。There is a difference between the construction of urban deep foundation pits with ultra-thick and high-permeable sand layers and general foundation pit construction.This article mainly takes the actual foundation pit construction project as an example,and uses the deep foundation pit dewatering construction technology without water-stop curtain to carry out the construction.The foundation pit construction technology and anti-floating construction technology were analyzed,and a construction technology that shortened the construction period and reduced the construction cost was explored.

关 键 词：深基坑施工 超厚砂层 施工技术
