摘要

软土地基的复杂性及不定性是影响深基坑支护工程的重要因素.结合珠江三角洲某基坑地质条件较差的工程实例布置详细监测方案，并对基坑支护结构的水平位移、基坑地下水位、支撑轴力、基坑周边地表沉降的监测数据进行了综合分析，获得一些有价值的基坑变形规律.通过分析基坑支护结构及周边变形的因素，确保了基坑工程的施工质量以及周边建筑的安全.

Abstract

The complexity and uncertainty of the soft ground have great influence on the support engineering of deep foundation pit. With regard to a project in the Pearl River Delta under bad geological conditions

it presents a monitoring design in detail. A comprehensive analysis of the monitoring data

such as the horizontal displacement of retaining structures

underground water levels

axial forces of struts

and surface settlement

has been conducted to get some valuable deformation laws to ensure the quality of the foundation pit construction as well as the safety of the surrounding buildings. The influencing factors of the foundation pit supporting structure and the surrounding deformation have also been analyzed.
