北京嘉铭中心酒店深基坑边坡支护结构变形监测

土钉墙与桩锚相结合的复合支护体系由于其安全性和经济实用性在深基坑支护工程中得到了越来越广泛的应用,为了进一步研究这种复合支护体系在深基坑施工过程中变形的大小、发展规律及对周围环境的影响程度,对该基坑的变形进行了系统的监测,并结合理论计算对监测数据进行了对比分析,为支护体系设计阶段中对变形的预测提供了有价值的依据。

DEFORMATION MONITORING OF THE SUPPORTING STRUCTURE OF DEEP EXCAVATION OF JIAMING CENTER HOTEL IN BEIJING

Because of the safety and economic practicality,the combination support system of soil nailing wall with composite pile-anchor has been more widely used in deep excavation supporting project. In order to do further investigation of the deformation extent of this complex support system in deep excavation construction process,the law of development,and the impact on the surrounding environment,the deformation of the excavation was systematically monitored. Combined with theoretical calculations,a comparative analysis of monitoring data was carried out. A valuable basis was provided for the deformation forecast in the design stage of the support system.
