摘要
结合北京地铁8号线二期某明挖基坑临时立柱沉降监测的数据和分析结果,提出了关于深大基坑回弹监测实施的一种新方法,并与其他基坑回弹监测方法进行优缺点的对比,对该方法在技术及经济上的可行性进行了阐述,并提出对基坑稳定状态评估中关于基坑回弹指标的应用。
This paper proposes a new monitoring method for rebound of deep foundation pit by analyzing temporary column monitoring data for pit excavation in Beijing Subway Line 8.Concerning merits and faults,this method has been compared with other methods for rebound of foundation pit.The feasibility of this method in technology and economy has been proved. Moreover,it also recommends the application of rebound index of foundation pit in the steady state evaluation of foundation pit.
