This National Science Foundation (NSF) Project Grant under the Engineering program (CFDA 47.041) provides $672,212 in funding to the University of Utah to conduct research focused on decoding the factors contributing to the instability of jointed rock slopes. The key objectives are to identify and quantify the distinct roles of natural rock fractures and the rock matrix in slope failures, which can pose significant risks to lives, infrastructure, and economies. The research approach integrates laboratory experiments and numerical simulations to reveal the mechanisms driving fracture evolution and progressive failure processes in jointed rock slopes. This includes characterizing the consequences of jointed rock failure, such as failing rock volume, runout distance, and velocity, as well as quantifying how the contrasting hydraulic and mechanical properties of the rock matrix and natural fractures influence slope stability. The project is expected to advance the state-of-the-art in rock mechanics and slope stability analysis, improve infrastructure safety, and foster an informed STEM workforce through cutting-edge research and education activities targeting high school students, youth-in-custody programs, and the general public.
