Study on the overall reflection coefficient of lightweight blast-resistant structures in soil
A differential equation of motion for the top slab components of blast-resistant structures in soil under explosive loading is established.The equation is solved for three cases:underdamped,critically damped and over-damped,resulting in calculation formulas for the overall reflection coefficient under different conditions.The influ-ence of unit area mass on the overall reflection coefficient is analyzed,and calculation formulas for the overall re-flection coefficients of lightweight high-strength blast-resistant structures and ordinary concrete blast-resistant structures are provided.The differences between the overall reflection coefficients of the two types of structures are discussed,which can serve as a basis for calculating the overall reflection coefficients of lightweight high-strength blast-resistant structures in soil.
