Construction method for shield tunnel to underneath pass through sensitive buildings in shallow-buried soft stratum
The invention belongs to the technical field of subway construction, and particularly relates to a construction method for a shield tunnel to underneath pass through sensitive buildings in a shallow-buried soft stratum. Through the four steps of construction preparation, combined type pre-grouting reinforcement treatment on the stratum, construction testing in a non-underpass section, and passingthrough the sensitive buildings by a shield tunneling machine, ground surface settlement and deformation are effectively controlled during underneath passing of the shield tunneling machine, and the safety of the sensitive buildings is guaranteed.
本发明属于地铁施工技术领域，具体涉及一种浅埋软弱地层中盾构隧道下穿敏感建筑群的施工方法。本发明通过施工准备、地层复合式预注浆加固处理、在非下穿段进行施工试验和盾构机穿越敏感建筑群四个步骤，有效的控制了盾构机下穿时地表沉降变形，保证了敏感建筑物的安全。
