Effects of particle size and cushioning thickness on the performance of rock-filled gabions used in protection against boulder impact

A gabion is one of the most commonly used cushioning layers to shield protection structures against boulders entrained in debris flow. Despite the prevalence of gabions, their cushioning performance is highly variable because of the wide range of rock sizes and cushioning thicknesses that are recomm...
