摘要
以上海东方金融广场为例,对土方开挖及支撑形成全过程地下连续墙深层水平位移监测数据进行分析和探讨,利用"时空效应原理"及"Rankine土压力理论"解释地下连续墙水平位移变形机理,并通过对监测数据变化规律的分析及时调整施工作业流程,最终确保了基坑开挖全过程围护结构自身及周边环境的安全。
Based on Shanghai Orient Financial Square, the horizontal displacement of the diaphragm wall in the process of foundation excavation and retaining is analyzed. By using principle of time space effect and Rankine earth pressure theory, the deformation mechanism of horizontal displacement of diaphragm wall is explained. According to the analysis of the changing law of monitoring data, construction process is adjusted to ensure the retaining structure and adjacent environment safe during the whole process of excavation.
