웹2024년 8월 9일 · Abstract. Several potential failure modes generally exist in rock slopes because of the existence of massive structural planes in rock masses. A system reliability analyses method for rock slopes with multiple failure modes based on nonlinear Barton-Bandis failure criterion is proposed. The factors of safety associated with the sliding and ... 웹1983년 1월 1일 · Empirical laws include models using logarithmic (Goodman, Taylor and Brekke 1968), generalized exponential (Malama and Kulatilake 2003), and hyperbolic (Bandis, Lumsden and Barton 1983) functions.
