| 摘 要： | 采用自由设站方法,解决了因基坑开挖施工引起周边土体变形而导致工作基点不稳定,影响监测精度的关键问题。通过TC2003高等级全站仪对监测点实测精度的分析和探讨,得出了自由设站加极坐标法测量基坑围护墙顶水平位移,能满足一级深基坑监测精度要求,可达到快速、准确反馈深基坑施工引起周边土体变形信息的目的。

| Abstract: | By free stationing,it solves the key problem of influencing monitoring precision which leads to basic work point unstable because of surrounding soil body deformation caused by excavating deep foundation pit.Through analyzing and discussing the monitoring point accuracy by TC2003 ETS,it gets horizontal displacement of enclosing wall top in foundation pit by free stationing and polar-coordinate measurement,it can meet the monitoring precision requirement of first-class deep foundation pit,achieve quick construction of deep foundation pit ,and feed back deformation information accurately. |
