Study on the mechanism of dynamic stress and fault displacement in deep formations induced by seismic waves
With reference to elastic wave dynamics theory and blasting seismic stress calculation method, combined with the refraction effect of seismic waves in the rock layer, the seismic wave acceleration is used as the basic data to analyze the force of the rock mass under the action of seismic waves.

| description | With reference to elastic wave dynamics theory and blasting seismic stress calculation method, combined with the refraction effect of seismic waves in the rock layer, the seismic wave acceleration is used as the basic data to analyze the force of the rock mass under the action of seismic waves. Taking the stress and deformation of the underground strata in Longmenshan foreland basin under the influence of Wenchuan earthquake as an example, the feasibility of the method in solving and analyzing the dynamic propagation of seismic waves in isotropic rocks is verified through calculation analysis and numerical simulation. At the same time, it was verified that the Wenchuan earthquake caused fault damage to the deep underground strata in the Longmenshan foreland basin. |
