Abstract Weak intercalation in redbed soft rock has the property of creep. Most of slope rock masses destabilize along the weak intercalation. So the selection of shear strength parameters is a key problem in the survey of slope. The shear creep experiments on samples with weak intercalation collected from two typical redbed soft rock slopes are performed. The results show that the soft intercalation is very significant in creep，which should be considered in the shear strength parameters. According to the analysis of long- and short-term shear strengths，it is suggested that the long-term shear strength is about 75% of short-term one.
