Rockfall Modeling Analysis and Mitigation at Mountainous Road, Saudi Arabia
Construction of mountain roads in western Saudi Arabia - where the rock masses are high-rising, steeply sloped, and full of geomorphological constraints - is a challenge. The Al-Hada mountain road, which is almost 22 km long, shows many incidents of rockfalls. A studied 100-m-long portion of mountain road lying along a man-made and natural sharp slope cut suffers from rockfalls incidents, mainly in rainy seasons. The rock masses are medium quality igneous rocks. The 50-m-high rock slope-cut along the road has no benches. The steep man-made rock slope cut is very close to the road, forming potential source areas for rockfalls. The RocFall computer program was utilized to perform the risk analysis, modeling and mitigation on the rock slope. Input parameters - such as block size, point seeder locations of blocks falls, slope angle, restitution coefficients, and slope roughness - were studied. These parameters were used to model rockfall characteristics, such as bounce height, kinetic energy, and translational and rotational velocities. The program modeled the proposed location, height and energy of the rockfall barriers and collectors. Modeling of the input parameters indicates the increase of the hit energy and end-point as the block size and restitution coefficients increase.
