摘要
洛阳新区排水东干渠隧道跨度大、埋深浅、地层软弱,施工中采用大管棚超前支护、CRD法开挖,辅以监控量测和信息反馈等施工手段,在控制施工沉降和确保施工安全方面取得了较好的效果,为以后的类似工程提供了依据和借鉴。
Dongganqu Tunnel in Luoyang new district is a large span shallow-buried tunnel in weak stratum. Large piperoof pre-support method, CRD method and assistant measures such as monitoring and information feedback are used in the tunnel excavation, which have achieved good effects in ensuring the construction safety and controlling the settlement of the freeway. This paper can provide reference for similar projects in the future.
