Assessment of rock mass decay in artificial slopes
This work investigates the time-dependent decay of rock masses exposed in artificial slopes and its impact on geotechnical properties and stability, emphasizing how weathering and environmental processes transform rock from competent to weakened states over engineering timescales. Through field observations and quantification of decay rates, the study explores how factors such as slope orientation, climate, and excavation methods influence the deterioration of different rock types, significantly affecting their strength and slope performance. The research results provide a framework for predicting the degree of rock mass weathering as a function of time and geotechnical parameters, thereby improving long-term stability assessments and design strategies for engineered slopes in weak and weathering-susceptible rock masses.
