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.
