摘　　要：砂质不良地质结构会增加工程施工难度与风险,影响工程进度与质量。为有效应对砂质不良地质环境影响,隧道施工需做好勘察作业,并采取合适的处理措施。文中以万荣隧道工程为例,对砂质不良地质进行了分析,采取挑顶利用旋喷桩技术,降低砂质不良地质的影响,使隧道工程施工得以顺利进行。In engineering construction,the presence of poor sandy geological structures can increase the difficulty and risk of construction,affecting the progress and quality of the project.In order to effectively deal with the unfavorable geological environment of sandy soil,it is necessary to strengthen the investigation of unfavorable geological structures of sandy soil during tunnel construction,take appropriate treatment measures,and avoid the impact of unfavorable geological environment of sandy soil on construction.Therefore,in this study,the Wanrong Tunnel project was taken as a case study to analyze the adverse geological conditions of sandy soil,and the use of jet grouting pile technology was adopted to reduce the impact of adverse geological conditions of sandy soil,promoting the smooth development of the tunnel project.
