Numerical Simulation of Soil-Structure Dynamic Interaction System under Blasting Load

Abstract:

Soil-Structure Dynamic Interaction (SSDI) is an important content of earthquake engineering and earthquake resistance of engineering structures. However, very few researches have been done on Pile-Soil-Structure Interaction (PSSI) under blasting vibration so far. In this paper, large finite element software ANSYS/LS-DYNA is used to simulate PSSI under blasting vibration. Research shows that the top displacement, acceleration and shear stress of piles are larger than the tip of piles, and the distribution laws are inverted triangles. What’s more, PSSI system sustains its vibration after the impact of blasting seismic waves, but the effect of the vibration is smaller than the blasting seismic waves does, which roughly conform to the measured results. These conclusions could provide theory basis for earthquake resistance of engineering structures and design of pile foundation.
