| 摘 要： | 基坑坍塌曾造成过人员伤亡的事故。为保证基坑开挖施工过程的顺利进行和周边建筑物的安全稳定,对北京地铁4号线西四车站通风道明挖基坑施工进行跟踪监测。分别运用全站仪和Topcon精密水准仪对侧壁桩顶的水平位移和周边地表的沉降位移进行了观测。监测结果显示,基坑侧壁最大水平位移为19 mm,而基坑周边地表最大沉降为10.42 mm,均没有影响到施工的顺利进展。监测取得了成功,为保证基坑的稳定和周围建、构筑物的安全做出了贡献。鉴于现场监测的重要意义,建议有关部门更应该重视并做好此项工作。

| Abstract: | Collapse of excavations causes accidents.To insure the excavation goes well and the safety of architectures nearby,a field monitoring program is carried out for the open-excavated project of the air duct of Xisi Subway station in Beijing.The total station optical electronic tacheometric theodolite is used to survey the lateral displacement and the pricise Topcon leveling instrument is used to survey the settlement displacement.Survey result indicates that the maximum lateral displacement is 19 mm and the ma... |
