摘要
以南京市康缘集团总部二期工程为例,在开挖过程中对桩顶水平位移、桩顶沉降、深层水平位移、支撑梁轴力等进行监测。分析结果显示,基坑的水平位移受支护结构和支撑梁刚度的影响较大。通过对监测数据的分析,具体明确地说明了该超大型深基坑的实际情况,可为类似基坑工程的支护结构设计等提供参考。
Taking the second phase of the headquarters of Nanjing Kangyuan Group as an example. During the excavation process, the horizontal displacement of pile top and pile top settlement, deep hori- zontal displacement, axial force of support beam has been monitored. The results indicate that the sup- porting structure and the stiffness of support beam play an important role in the horizontal displacement of foundation pit. Through the analysis of monitoring data, the actual situation of the super large deep foun- dation pit is clear and definite. It can provide reference for the optimization design for the similar sup- porting structure of foundation pit engineering.
