摘要
在城市地铁施工中,由于基坑开挖周围环境复杂,易引起土体扰动,可能对建筑物和地下管线造成破坏,甚至引起基坑失稳。深基坑开挖作为地铁车站施工过程中的重要环节,建设单位应从实际情况出发,采取与之相适应的开挖施工技术,并按照规范将各环节施工落实到位,确保工程质量。以工程实例为背景,根据地铁车站深基坑的基本施工条件,探讨相适应的开挖施工技术,以供参考。
In urban subway construction,due to the complex surrounding environment of foundation pit excavation,it is easy to cause soil disturbance,which may damage buildings and underground pipelines,and even cause foundation pit instability.Excavation of deep foundation pits is an important link in the construction of subway stations. The construction unit should proceed from the actual situation,adopt appropriate excavation construction techniques,and implement all aspects of construction in accordance with the specifications to ensure the quality of the project. Based on engineering examples as the background,this article discusses suitable excavation construction techniques for reference based on the basic construction conditions of deep foundation pits in subway stations.
