摘　　要：为解决存在大量障碍物的厚砂性土层清障后,地下连续墙施工面临的难题,结合上海某地铁车站基坑围护的施工实例,研发了一种在厚砂性土层中密集清障区的超深十字钢板接头地下连续墙施工关键技术,以期为今后类似工程的施工提供借鉴。In order to solve the problems encountered in the construction of diaphragm walls following the clearance of substantial obstacles within thick sandy soil layers,combined with the construction example of foundation pit support of a subway station in Shanghai,a key technique for the construction of ultra-deep cross steel plate joint diaphragm walls in the dense barrier clearance area of thick sandy soil layers is developed,with the aim of providing reference for the implementation of similar engineering projects in the future.
