摘　　要：通过对浅埋偏压破碎地段隧道的工程特点分析,采用注浆长管棚施工工艺的力学作用机理,对典型隧道工程注浆长管棚加固技术方案进行研究,从长管棚施工到长管棚注浆,总结了部分经验,以求为浅埋偏压破碎地段隧道工程建设提供技术参考,并在同类工程中加以推广。Based on the analysis of the engineering characteristics of the tunnel in the shallow buried eccentric pressure broken section,the mechanical action mechanism of the grouting long pipe shed construction process is adopted,and the reinforcement technical scheme of the grouting long pipe shed in typical tunnel engineering is studied.From the construction of the long pipe shed to the grouting of the long pipe shed,some experience is summarized,so as to provide technical reference for the construction of the tunnel in the shallow buried eccentric pressure broken section,and promote it in similar projects.
