摘　　要：利用地震折射法对某公路隧道进行勘探,并利用获得的地下岩体的波速,根据有关规程对隧道洞线附近的围岩进行分类,其分类结果和后期的勘探结果一致,说明地震折射波法在隧道围岩划分中有良好的应用效果。Taking seismic refraction wave method, one roadway tunnel is investigated, and using the velocity of rock wall got by the method, the surrounding rock near the tunnel axis is classified based on the correlative criteria. The classification results of surrounding rock are accorded with those by the drilling results. The re- sults show that the seismic refraction wave method has well effect applied in classification of surrounding rock of tunnel.
