摘要:Due to the information technology development the numerical modelling in the traffic structures engineering finding the application. Even in the traffic effect on the geological environment and soil. It this case two mechanical systems are interactive and acting to each other. This special type of interactive task is usually solves by using Finite Element Method (FEM). In both mechanical systems propagates the dynamic strength and strain effects. The Traffic Seismicity (TF) in the elastic half space is possible to solve in the time and the frequency domain. The paper contains theoretical approach of the two numerical simulations in the TS task. For this type of the FEM simulations the various numerical systems were used.
