深基坑围护结构力学变形监测技术

Monitoring Technology in Mechanical Deformation of Exterior-protected Constructions in Deep Foundation Ditch

主要介绍了北京地铁五号线和平西桥车站施工期间的力学变形监测技术,阐述了力学变形监测工作在城市松散含水地层深基坑围护桩施工时的一些技术要求和措施,文章系统地总结了本工程中的力学变形监测技术,为今后类似工程变形监测工作积累了宝贵的经验。

This paper presents the monitoring technology in mechanical deformation that is used in the 5th line subway of Beijing, especially in the constructing period of Hepingxi bridge station. It describes the requests and measures when you undertaking these works to the exterior-protected constructions in deep foundation ditch under the condition of aquifer water-bearing stratum. At the same time, all these technologies have been summarized systematically, which can provide precious experiences for the similar engineering work of monitoring in the future.
