摘要
结合合肥市府广场地下通道工程,详细介绍了在饱和淤泥质地层条件下采用长管棚结合注浆小导管超前支护、短开挖和强支护等综合浅埋暗挖施工技术。工程结果表明,在复杂环境下采用暗挖法施工是可行的,并可实现洞内施工安全和地面沉降控制要求,避免了明挖施工对城市交通的干扰。所得施工经验对合肥地区类似地下工程具有一定的指导意义。
Based on underground passage eng.ineering of SHIFU square, this paper introduces construction technology of shallow embedded tunnel, including, advance support of long pipe and small duct grouting, short excavation and strong support in saturated silt stratum. The results of engineering show that Shallow tunnel construction method is feasible under complex environment; this method is satisfied with the safety of construction inside tunnel and control standards of surface subsidence, which can solve the problems of urban transportation caused by open--cut method. This construction experience can act as theoretic basis and reference for the design and construction of similar underground engineering later.
