In tunnel construction, hole serious bias twin arched tunnel is the difficulty, and we should focus on the research of the control of hole bias landslides and land subsidence tunnel in tunnel construction. Based on the study of basic geological environmental conditions, through the analysis on tunnel surrounding geotechnical physical parameters and the tunnel wall rock mechanical property indicator, this paper conducts construction technology research on tunnel's level and vertical linear construction, hole lining construction and middle wall. Finally, appropriate conclusions and recommendations are given.%在隧道工程施工中,洞口严重偏压联拱隧道是施工中控制的难点,对洞口偏压段塌方和地面沉降的控制是隧道施工中需要我们去设计研究的重点.本文在介绍研究区基本地质环境条件的基础上,通过分析隧道周边岩土体力学参数及隧道围岩的力学性质指标,对隧道的平、纵线形施工、洞身衬砌施工以及中隔墙分别进行施工技术研究,并在最后给出相应的结论和建议.
