Limit states design checks have been developed for geotechnical loads using a strain-based design format. The application of these checks requires the user to develop probability distributions for the maximum strain demand and minimum strain capacity. These checks are provided for both local buckling and tensile rupture, and they are calibrated to meet specified risk-consistent reliability targets. This paper presents a detailed description of the safety factors developed as part of the limit states design checks, and the implications of their use in the assessment of pipelines in moving slopes.
