The Principle and Idea on Reducing Earthquake Disasters Using Light Reinforced Soil

Abstract

In order to reduce the hazards of earthquake disasters on human, basic principle of reducing vibration is discussed by establishing passive vibration isolation model. The calculation results show vibration can be reduced by isolation materials whose deformation modulus (stiffness) should be smaller and damping should be appropriate. Light reinforced soil is a good man-made material, its all physical mechanical parameters can be changed, and anti-pull capacity of soil can be increased. According to the basic principle of reducing vibration, reducing vibration idea using light reinforced soil is brought forward, and the idea has a very important significance for research on reducing earthquake disasters from the angle of ground and foundation.
