In the western part of Sichuan province of China, moraines are widely distributed along the Valley of Zagunao River. The moraines at high altitude have deformed constantly under the influence of precipitation. It is considered as a severe threat to the local community. By on-site geological investigation and lab experiments, the sensitivities of moraines under different saturation rates are observed. The cohesion and friction angle both have negative correlations with the saturation rates of the morainic materials. Traditional mechanical strength models for unsaturated soil analysis failed to explain the mechanical characteristics explicitly. A revised Mohr-Coulomb criterion formula with an added cohesive compensation is proposed in this research to compute the unsaturated strength. The revised criterion accurately predicts the strength and is valuable for future research of special types of breccia.
