逆作法基坑工程监测综述

Review of the Monitoring of Top-down Excavation

总结了我国逆作法基坑工程建设、规范及监测的发展历程,以及规范关于逆作法基坑监测的规定。讨论了逆作法基坑工程几个关键项目的监测方法,包括立柱差异沉降监测及立柱与围护墙差异沉降监测、结构梁板内力监测、坑底隆起监测;指出了目前逆作法基坑监测中存在的问题,最后展望了逆作法监测的发展趋势。

Firstly, the development process of construction, specifications and monitoring of top-down excavation are summarized as well as the specification of monitoring on the top-down excavation. Secondly, several key project monitoring methods are discussed, including the monitoring of column differential settlement, internal forces of structural slab and uplift at the bottom of the foundation excavation. Then the current problems in top-down excavation monitoring are pointed out. Finally, the trends of monitoring of top-down excavation are predicted.
