摘要
Abstract
The subway station is located in a bustling urban area,with entrances and exits set on sidewalks on both sides.Due to the influence of underground pipelines and surrounding environment,the pedestrian passage at Zhoushi Road Station is constructed using shallow buried and concealed excavation.During the excavation and construction process of the foundation pit at the affiliated entrance and exit,more and more flat top straight wall structures have emerged.When constructing the second lining of a flat top straight wall structure,temporary support measures can be taken in two forms:one is to replace the support before the construction of the second lining,and the other is to replace the support after the construction of the second lining.By summarizing past construction experience and relying on the practice of the Zhoushi Road Station Street Crossing Project of Shenzhen Metro Line 12,a set of construction techniques for dismantling and supporting the secondary lining after the formation of a hidden excavation flat top straight wall section are studied.It has the advantages of simple operation,high safety,cost saving,reliable quality,and time saving.At the same time,corresponding construction methods and key technologies are summarized.关键词
