摘要
本文介绍了天津铜锣湾广场深基坑工程开挖实例。通过对开挖过程中的支护结构内力、坑周土体水平位移等的现场监测和数值模拟分析,讨论了基坑开挖过程中支护结构受力的特点及其对周围环境的影响,得到了基坑周边土体水平位移的变化规律,为考虑施工因素的支护结构设计提供了依据。
In this paper, the excavation work of deep foundation pit for Tianjin Causeway Bay Plaza is propesed. A test section was established in construction site. Bracing responses and lateral displacement of soils were measured. By construction the monitoring data and numerical analysis, the characteristics of internal force of bracing system and soil horizontal displacement are obtained. Through these analyses, the law of horizontal displacement in ambient soil was obtained, and the measures considering the construction factors can be adopted for the ring beam structure design and displacement control.
