摘　　要：为研究浅埋偏压段的围岩稳定性,以烟海高速解家河隧道为例,采用地质雷达进行了地质超前预测,并针对探测结果,进一步优化施工方案,确定了超前注浆、超前小导管的施工方法。最后采用现场监控量测的方法对浅埋偏压段进行监测,结果表明,监测数据稳定,所采用的施工方案可行;浅埋偏压段洞室稳定,确保了隧道施工的顺利进行,对类似工程具有一定的借鉴意义。In order to study the surrounding rock stability of shallow buried and unsymmetrical loaded section, the geo- logical radar was used to perform advanced geology forecast by taking the construction of Xiejiahe Tunnel of Yanhai Highway as an example. Based on the forecast results, the construction program was optimized and the leading ductule injecting was adopted. The site monitoring was also employed and the results demonstrated that the data were stable and the construction program was feasible. The shallow buried and unsymmetrical section of the Xiejiahe tunnel was stable enough to assure tunnel construction going on smoothly. Furthermore, it could provide reference for similar engineerings.
