摘　　要：隧道洞口段施工是整个隧道建设中的重点和难点。依据洞口段地形及地质条件,制定合理的进洞方案不仅能避免工程问题的发生而且能够减少对生态环境的破坏。以浪风关隧道出口为例,总结浅埋偏压地段、松散坡积体进洞技术方案、施工组织、施工工艺等技术要点,为类似的隧道工程施工借鉴与参考。The construction of tunnel entrance is always the key and difficult in the whole construction process.According to the terrain and geological conditions of the portal section,making a reasonable tunnel entrance plan can not only avoid the occurrence of engineering problems,but also reduce the damage to the ecological environment.Herein,taking Langfengguan tunnel portal as an example,the technical points of shallow bias tunnel crossing slope deposit are summarized,such as tunnel entrance plan,construction organization,and construction technology,which may provide reference of similar tunnel engineering construction.
