 ABSTRACT

There are many theories founded to investigate the soil and rock detonation. The protection research with influence to the peripheral structure has become the important topic. The pressure in the surrounding structures is affected by materialsí character and rarefaction waves of air etc. The influence to the peripheral structure has the direct relations with stress wave attenuated in soil and rock. Surrounding structures affected by the blasting load in soil and rock is investigated with numerical simulation by changing the materials. The nonlinear procedure ANSYS/LSDYNA970 is used. The results indicate that the pressures in the surrounding structures are affects by materialsí character and rarefaction waves of air etc. Some attenuation laws of pressures are obtained.

Keywords: soil and rock, concrete, blasting load
