摘要
以漳州市某深基坑开挖施工为例,采用现场监测和三维有限差分计算软件FLAC3D数值模拟方法来分析和研究深基坑施工过程中对周边市政管道沉降和位移的变化规律。研究结果表明,数值模拟结果与该深基坑现场实测数据较吻合,最大测点位移为10.80 mm,施工中基坑侧壁节点对周边管道影响较大,在深基坑开挖施工过程中应重点监测和支护,该研究成果为后期类似深基坑工程的开挖施工方案提供参考。
This paper takes the excavation construction of a deep foundation pit in Zhangzhou City as an example,employing on-site monitoring and the three-dimensional finite difference calculation software FLAC3D for numerical simulation to analyze and investigate the variation patterns of settlement and displacement of surrounding municipal pipelines during the deep foundation pit excavation process.The research results indicate that the numerical simulation results are in good agreement with the field-measured data of this deep foundation pit.The maximum displacement at the measurement point is 10.80 mm.The nodes on the sidewall of the foundation pit have a significant impact on the surrounding pipelines during construction.Therefore,key monitoring and support measures should be implemented for the sidewall nodes during the deep foundation pit excavation process.This research finding provides a reference for the excavation construction schemes of similar deep foundation pit projects in the future.
