港湾广场一期深基坑变形监测与分析
摘要:深基坑施工变形监测是信息化施工的重要内容,以广州港湾广场(一期)深基坑工程为例,通过对开挖过程中土体水平位移、支护结构侧向位移、支护结构内应力、沉降等监测,结合围护结构的强度检测,采用反演分析对基坑变形进行数值模拟,预测不同开挖深度时基坑的位移变形量,实际监测结果与预测值基本一致,为基坑的设计和施工提供可靠的依据。
Abstract:Deformation monitoring of deep foundation pit is an important content of information construction. In the excavating process of the deep foundation pit project of Gangwan Plaza (Phase 1), according to the horizontal and lateral displacement, internal stress of support structure, subsidence monitoring and so on, combined with intensity detection of perimeter structure, use inverse analysis method to simulate foundation numerical deformation, and forecast foundation pit deformation at different depth. The actual monitoring result is consistent with the forecast value basically, and the reliable basis is provided for foundation pit design and construction.
