Abstract
In order to study the influence of landform slope on the propagation law of shock wave, the explosion experiments and numerical simulations were conducted on the landforms with 0°, 10°, 20°, 30° and 40° slopes, and the data of shock wave overpressure and impulse under different landform conditions were obtained. Results show that the peak pressure and impulse increase with increase in slope angle, and decrease with increase in relative distance. When the slope angle is 40°, the peak pressure and impulse at measuring point 3 (near the initial position of slope) are 2.36 and 1.88 times of that on flat ground, and the effect of landform slope is obvious. Besides, the empirical formulas of peak air pressure and impulse between flat ground and sloping ground within the experimental range were established by fitting the experimental and simulation data, which could provide reference for engineering practice.
