摘要
从地质雷达的基本原理出发,结合沙坝一号隧道DK22+267～DK22+292段软塑状黏土溶洞的探测实例,总结了双曲线波、阶梯状复合波、强反射波以及复合波条带区域等软塑状黏土溶洞的雷达图像响应特征,对其他类似工程地质条件下的超前地质预报技术有一定的指导意义。
Based on the basic principle of geological radar,combined with the soft plastic clay cave detection practice in Shaba No.1 tunnel DK22+267～DK22+292 section,this article summarizes some radar image response characteristics of soft plastic clay cave,such as the hyperbolic wave,stepped composite wave,strong reflection wave and composite wave band area,which will provide positive guides to advanced geological forecast technology in some other tunnel constructions under the similar geological condition.
