摘　　要：以包谷山隧道浅埋偏压段工程为依托,通过对半明半暗施工技术进行详细阐述,结合现场监控量测结果,对该技术的施工可靠性进行了分析研究。结果表明,在偏压区段采用该工法施工能够有效降低对周围围岩的扰动,但仍需加强对明挖区间段的监测,以便及时采取相应措施。此外,针对数据分析结果,提出了一系列相应的施工指导措施。This paper is based on the project of shallow buried bias section of Bao Gu Shan Tunnel,through the half-bright and half-dark construction technology is elaborated in detail,combined with on-site monitoring and measurement results,the reliability of the construction of this technology is analyzed and researched,and the results show that,in the bias section of the construction of the construction method can be effective in lowering the disturbance to the surrounding surrounding surrounding rock,but it is still necessary to strengthen the monitoring of the open-cutting interval section in order to take corresponding measures in a timely manner.In addition,in view of the results of the analysis of the data,this paper proposes a series of corresponding construction guidance measures.
