摘要

摘要: 由于影响深基坑变形因素较多,在不同的场地施工条件下其可控因素不同,很难准确预测基坑变形量的大小,不能为基坑监测提供准确可靠的预警值,有必要针对某特定区域和支护结构进行深基坑变形的预测分析。针对杭州地区的基坑监测数据,通过大量数据的统计分析,得到基坑支护结构与地面沉降和坑底隆起的关系,以及变形特征和变形值大小;然后根据基坑的重要性和周围建筑物重要程度进行分级,确定基坑变形的控制值,作为基坑监测的预警值,以确保基坑施工安全。通过监测数据分析发现针对杭州地区有较好的适应性。

Abstract: Deformation prediction of deep excavations is difficult, and pre-warning value is not accurate and reliable because there are many factors to affect their deformation and different controlling factors in different places. It is essential to predict and analyze deformation of deep excavations according to special area and supporting structure. Statistical analysis is conducted to analyze the mass data of monitoring in Hangzhou City to gain the relationship between deformation of supporting structures and surface settlement and bottom upheaval as well as the deformation characteristics and values. Then, the degree of excavations is classified according to its importance and the degree of building importance. Finally, the controlling value of excavation deformation is put forward as the pre-warning value so as to ensure the construction safety of excavation. The conclusion is adaptable to predict the deformation of excavations in Hangzhou.
