基于浅埋隧道塌方处治技术分析

Based on the Treatment Technology of Shallow Buried Tunnel

随着全国公路工程建设的快速发展,隧道安全施工问题愈发重要,特别是浅埋式隧道的施工安全。本文以岳圩口岸联线公路汉邦1号隧道为例,深入分析了隧道塌方的原因,主要包括地质条件、岩层受力、围岩稳定性及雨水渗透等因素。针对塌方情况,项目部采取了多项应急处理与处治措施,如加强监控量测、注浆加固、回填反压等,成功控制了塌方影响范围,确保了施工安全与质量,同时详细阐述了塌方处理的过程与效果,以期为类似隧道工程提供参考与借鉴。

With the rapid development of highway engineering construction in China,the safety construction of tunnels is becoming more and more important,especially the construction safety of shallow buried tunnels.Taking the Hanbang No.1 Tunnel of Yuewei Port Link Highway as an example,this paper analyzes the causes of tunnel collapse in depth,mainly including geological conditions,rock strata stress,surrounding rock stability and rainwater infiltration.In view of the collapse situation,the project department has taken a number of emergency treatment and treatment measures,such as strengthening monitoring and measurement,grouting reinforcement,backfilling and counterpressure,etc.,which successfully controlled the impact range of the collapse and ensured the safety and quality of construction.This paper elaborates the process and effect of collapse treatment,in order to provide a valuable reference for similar tunnel engineering.
