摘要

双基坑大直径双环梁支护体系是一种新型的基坑支护结构形式。通过对天津铜锣湾广场基坑工程中的环梁支撑内力和坑周土体水平位移的现场施工监测和数据结果分析，讨论了基坑开挖过程中环梁结构受力的特点以及对周围环境的影响，得到了基坑周边土体水平位移的变化规律，为考虑施工因素的环梁结构设计提供了依据。

Abstract

A new support system is applied to excavation of double foundation pits. In this system

double large-diameter annular arched girders structural system is used. By construction monitoring in Tianjin Cause Bay Plaza

data about internal force of supporting system and horizontal displacement of soil are obtained. This article analyzes these data and also discusses the characteristic of internal force changing in annular arched girders and influence on environment in the course of excavation. By these analyses

the law of horizontal displacement in ambient soil is drawn; and the measures considering the construction factors can be adopted for the annular arched-girder structure design.
