摘要

南京某大厦深基坑采用了悬臂支护结构、单层支点混合支护结构、钻孔灌注桩连拱支护结构三种支护型式，根据该基坑开挖施工过程中获得的现场测试数据，分析和研究了在相同的工程、水文地质和施工条件下，不同支护结构和外侧土体变形的时空效应。

Abstract

Cantilever retaining structure

single-pivot mixed retaining structure

borehole cast-in-place concrete pile multi-arch retaining structure are adopled for a certain deep-foundation pit excavation in Nanjing city. Based on the in-situ measured data in excavation and construction of foundation

the time-space effects of deformations of different retaining structures and outside soil under the same engineering geological and hydrogeological conditions and construction condition are studied.
