摘要
佛山市广佛线朝安地铁站D出口基坑因长边较长,深度较深以及周边环境等特点,在基坑开挖施工过程中对基坑周围土体及支护结构和周边环境有必要进行监测。针对监测的基坑深层水平位移、周边水位变化、支撑轴力数据进行处理与分析。监测成果表明,基坑土体的侧向变形与内支撑轴力之间有对应关系,合理设计内支撑位置以及数量对于控制土体的侧向变形幅度影响较大,同时,也为基坑信息化施工提供了基本手段,使得现代基坑施工和监测得到了动态体现,可供类似工程参考借鉴。
It is necessary to monitor the earth mass,support structure and environmental condition around the foundation pit of D entrance of Guanzhou-Foshan Metro Line’s Chaoan Station in Foshan Because of such the characteristics as the long length,deep depth and complex environment of the foundation pit.Here,the horizontal displacement,settlement,axial force,surrounding buildings and other data of the foundation pit are treated and analyzed.The monitoring results indicate that the lateral deformation of the earth mass is associated with the axial supporting force,so the rational design for the interion supporting position and quantity has great influence on the controlling of the lateral deformation of the earth mass.At the same time,the monitoring results also provide basic measures for informational construction and reflect the modernized characteristics of the construction and monitoring of foundation pit,which could be used for the refference of similar engineerings.
