| 摘 要： | 结合深基坑变形机理和工程案例,对厦门某地区一深基坑的周边土体深层水平位移、围护桩水平、竖向位移、地下水位等监测成果进行分析,以研究深基坑施工过程中的变形特性和变化规律.研究结果表明:工程地质条件、基坑开挖深度、周边荷载以及支撑拆撑过程等是引起深基坑变形及稳定性的主要因素;合理结构设计和土方开挖方案,并根据监测数据实时指导施工和采取合理控制变形的措施是确保基坑安全的基础.

| Abstract: | The deformation mechanism of a deep foundation pit was analyzed. Combining with engineering case in Xiamen, the monitoring results were comprehensively analyzed about deep horizontal displacement of soil around foundation pit, horizontal and vertical displacement of fender piles, underground water level and the stress of beam monitor, etc. Deformation and its laws of deep foundation pit construction were attained. Research results showed that geology condition, the surrounding load, the depth of excavation and support removing process were the main factors that cause deformation and stability of foundation pit. It was the basis to ensure the safety of foundation pit that structure design and earthwork excavation were reasonable. It could guide the construction and take reasonable measures to control deformation according to the monitoring data in real time. |
