本文基于广州某工程建筑基坑监测项目的实践,通过对该工程特有地质情况的分析和对深基坑实时动态变形监测,结合支护体变形特征,探索应用了一种锚索支护桩+角支撑+预应力的一种深基坑支护型式。并进一步优化设计了基坑监控量测方案,结果表明,监测点位移与沉降均符合安全标准,围护结构体系可靠,基坑边坡稳定,为以后类似工程的设计和施工提供参考。
Based on the practice of a construction project of foundation pit monitoring project in Guangzhou and through the analysis of the unique geological conditions of the project and the monitoring of deep foundation pit dynamic deformation in real time and with the deformation characteristics of the support body, Angle support + prestressed a deep foundation pit support type. The results show that the displacement and settlement of the monitoring points are all in line with safety standards, the structure of the retaining structure is reliable and the slope of foundation pit is stable, which can provide references for the design and construction of similar projects in the future.
