The technique is a powerful tool for the numerical solution of nonlinear differential equations. The technique has its origins in the parameter continuation method combining with the shooting method, Newton-Raphson method and Floquet theory. The influence of internal parameters on the vibroimpact systems dynamic behavior was carried out using the above mentioned methods and Poincare sections. The influence of the rigidity parameters and elastic modulus of contacting bodies on the force of dynamic contact interaction was asnalysed. An effective approach to the analysis of wave propagation in poroelastic solids was developed. Using the developed modyfication of the boundary integral equation method the consolidation of soil mass under pulsing loading was investigated. The investigation of the rolling stock load influence on the multi-storey building being under construction in the close to the railroad area has been conducted. FEM calculation models of the ballast prism and the building in the interaction with the base soil were created. The acceleration of the soil at the depth of the foundation laying was obtained and, as the result, its influence on the dynamic behavior of building was evaluated.
