摘要
在深基坑土方开挖过程中,通过对基坑支护结构进行系统的监测及其分析,才能全面掌握支护体系的安全状况,确保工程顺利进行。本文结合南京鹏欣水游城大型深基坑施工监测的工程实际,对其围护结构及支撑体系依据监测数据进行系统分析并进行有限元模拟。阐述了基坑开过程中支撑体系应力变化发展的规律,并对深基坑支护设计施工监测中需注意的问题提出了意见。
In the excavation process of deep foundation pit,it can control the security situation of foundation through monitoring and analyzing the supporting structure to ensure that the project is carried out smoothly.This paper combined the practice of Nanjing Xinpeng water-city deep foundation pit,it analysis the monitoring data and simulate the envelope structure and support system using Finite Element Analysis,describe the law of stress development of support system in the process of excavation.This paper also gives advice on designing on supporting frame and submits opinions on construction and monitoring of deep foundation pit.
