摘要
本文以新加坡滨海湾金沙综合娱乐城P8402标项目的深基坑开挖支护为例,通过ValetParking(北基坑)信息化施工监测数据的反馈,运用位移反分析法,实现北基坑减少一道钢支撑的施工设计优化。详细阐述了位移反分析法成功运用的过程,通过有限元数值分析法,分析了P8402工程中的设计优化过程,为位移反分析法的研究和应用提供有益的借鉴。
In this paper,the construction of deep excavation pit of P8402 Contract of Singapore's Marina Bay Sands integrated resort is taken as an example.Based on the monitoring data during Valet Parking(North Pit) construction,according to the displacement back analysis method,construction design is optimized so as to reduce a steel strut in north pit construction.The paper elaborates the successful process of applying the displacement back analysis method.Finite element numerical analysis is used to analyze the design optimization process of the P8402 project,which would be a useful reference for study and application of displacement back analysis.
