摘要
隧道作为具有高风险的地下暗挖施工项目,在地下作用下极易引发地层失稳、周围建筑物倾斜倒塌、地表沉陷交通中断、群死群伤等恶性事件.文章以河南省洛阳市某高速公路下穿既有线浅埋暗挖隧道施工为背景,论述了实际施工采取的各项有效措施及产生的效果,旨在最大限度地降低在复杂环境中施工的风险,总结施工经验,确保工程建设顺利推进.
Abstract
As a high-risk underground undercutting construction project,the tunnel is easy to cause vicious events such as stratum instability,surrounding building tilting and collapsing,surface subsidence,traffic interruption,and mass casualties under underground action.Based on the shallow-buried bored tunnel construction of an expressway in Luoyang City,Henan Province undercrossing an existing line,this paper discusses the effective measures taken in the actual construction and the effects,aiming to minimize the risk of construction in complex environment,summarize the construction experience,and ensure the smooth progress of the engineering construction.
