摘要
文章以某城市地铁盾构隧道与既有建筑物桩基相冲突的工程实例,阐述了特殊条件下,不做桩基托换,采用盾构机直接截桩穿越建筑物桩基的关键技术措施,最终在确保建筑物安全的同时,成功地解决了制约整条地铁线路通车的关键难题。
This paper illustrates the key of a metro shield tunnel in a city that conflicts with a building foundation. The key to using a shield machine to directly cross a building pile foundation without a pile foundation under special conditions is described. Technical measures, while ensuring the safety of buildings, have successfully solved the key problems that constrain the opening of the entire subway line.
