Predicting the occurrence of landslides is important to prevent or reduce loss of lives and property. The stability of rock slopes is often dominated by one or more locked segments along a potential slip surface; these segments have relatively high strength and accumulate strain energy. Locked segments can be preliminarily classified into three categories: "rock bridge", "retaining wall" and "sustaining arch." Coupling a one-dimensional renormalization group model with the strain-softening… 

Rock slope stability analysis considering the effect of locked section

The locked section is a kind of geological structure that is commonly found in natural slopes. The instability criterion of the slope with a locked section structure is not yet studied. In accordance
