摘　　要：介绍了相干波的理论原理 ,并从该理论出发 ,建立了隧道衬砌模型 ,分析了隧道衬砌检测中相干波的形成机理及其与衬砌背后空隙大小的关系 ,从而得出了地质雷达在隧道质量检测中衬砌背后空隙大小的计算方法 .Principles and theories of enhanced wasves were introduced. On the basis of this, the tunnel ram model was established. And the forming mechenism of enhanced waves as well as the sizes of porosity were analyzed. As a result, the method for calculating the size of porosities in the back of the tunnel ram has been obtained and proved to be a good one.
