摘　　要：研究采用TSP地震波法探测的隧道岩石弹性模量与超声波法检测的弹性模量之间的关系,首先统计了超前地质预报工作中TSP地震波法预测的岩石弹性模量,然后选取部分段落钻取岩石芯样,开展室内岩石超声波测试,得到岩石的弹性模量,比较讨论了不同围岩段落内岩石弹性模量的变化情况。In order to analyze and study the relationship between the elastic modulus of tunnel rock detected by the TSP seismic wave method and the elastic modulus detected by the ultrasonic method,the elastic modulus of the rock predicted by the TSP seismic wave method in the advanced geological prediction work was first counted,and then some sections of the rock core samples were drilled to carry out the indoor rock ultrasonic test to obtain the elastic modulus of the rock,and the changes of the elastic modulus of the rock in different surrounding rock sections were compared and discussed.
