轨交车站深基坑工程对周边不同基础建筑物保护效果的分析

Analysis on Protective Effect of Deep Foundation Pit Engineering of Rail Transit Station on Adjacent Buildings with Different Foundations

地下工程设计中,基坑变形控制是预防工程环境风险的关键,也是基坑设计分析的重点。结合上海轨交12号线汉中路站深基坑工程的实践,介绍了对工程周边地面建筑实施的保护措施和监测的过程,分析了对不同基础形式建筑物保护的效果,可供类似工程参考和借鉴。

In underground engineering design,foundation pit deformation control is critical to prevention of engineering environmental risk and also a major concern of foundation pit design and analysis.With the practice of deep foundation pit engineering for Hanzhong Road Station of Shanghai Metro Line 12,this article introduces protective measures taken for surface structures adjacent to the project and relevant monitoring process and analyzes the protective effects on buildings with different foundation forms.The said practice proves a useful reference to similar projects.
