摘　　要：该研究以当阳至远安铁路毛家坡隧道和槐树店隧道为对象,开展了地震波法和地质雷达法的综合应用工作。结果表明,对于毛家坡隧道,地震波法和地质雷达法的溶洞位置预报精度分别为87.18%和92.31%;对于槐树店隧道,两种方法的溶洞位置预报精度则分别为92.00%和90.32%,且地质雷达法对溶洞规模的预报精度达到了91.43%。因此,相比于单一的物探法,综合应用地震波法和地质雷达法可提高对不良地质体位置和规模的预报精度。This study comprehensively applies Seismic Reflection Wave(SRW)method and Ground Penetrating Radar(GPR)method to the Maojiapo Tunnel and Huaishudian Tunnel of the Dangyang to Yuan'an Branch Railway.The results show that,for the Maojiapo Tunnel,the accuracy of predicting the location of karst caves using SRW method and GPR method is 87.18%and 92.31%,respectively.For the Huaishudian Tunnel,the accuracy of the two methods for predicting the location of karst caves is 92.00%and 90.32%,respectively,and the accuracy of the GPR method for predicting the scale of karst caves reaches 91.43%.Therefore,compared to a single geophysical prospecting method,the comprehensive application of SRW method and GPR method can improve the prediction accuracy of the location and scale of unfavorable geological bodies.
