摘要
在富水砂卵石地层中,盾构隧道交叉重叠换边施工尚属首次,为解决盾构掘进通过后地表不发生较大沉降、不对道路及管线造成破坏,在工程实施过程中采取了盾构掘进控制、地表注浆加固、洞内顶管注浆加固及施工监测指导施工的信息化施工技术,实践证明是比较成功的。
For the first time, the alternated construction technique is applied to a shield-driven tunnel in a water-abundant sandy pebble stratum. In order to avoid sizeable ground settlements and damage to roads and pipelines after shield driving, the information oriented construction techniques of shield driving control, ground grouting reinforcement, pipe-jacking grouting reinforcement and construction monitoring were applied. These measures proved to be effective and successful.
