摘　　要：通过对充水型、不充水型陷落柱地质模型的研究 ,发现绕射波的射线穿过陷落柱内的低速体产生明显的时间延迟 ,并且充水型陷落柱比不充水型陷落柱的延迟绕射波延迟时间要长 ;由延迟时间推算出陷落柱内的充填速度 ,据此来分析陷落柱的充水性 .The geological models for both water filled and non water filled subsided columns were researched. The result shows that the penetration of diffraction wave rays through the low velocity zone in subsided column results in an obvious time delay, with the water filled subsided column being longer in delayed time than that of the non water filled subsided column. The delayed time can be used for calculating the filling velocity and the water filling situation of the subsided column. This method can be used to analyze directly the water filling situation of subsided columns from the seismic time section.
