Study on the Evolution Law of Internal Force and Deformation and Optimized Calculation Method for Internal Force of Cantilever Anti-Slide Pile under Trapezoidal Thrust Load

The evolution law of internal force and deformation an anti-slide pile affects the slope stability prevention design in a significant way. Based on similarity theory, test system for bearing characteristics cantilever was constructed, physical model under trapezoidal thrust load carried out. distribution laws were revealed, optimized calculation method proposed by taking elastoplastic steel bars concrete into consideration. Furthermore, numerical employed to conduct parametric analysis pile. results show that whole process stress can be classified as uncracked stage, cracks emerging developing yielding–failing stage. In bending moment calculated traditional is smaller than established this paper. no longer applicable stage developing. lateral displacement are negatively positively correlated with strength material, respectively, influence deterioration bars’ ultimate performance more obvious strength. capacity could not significantly improved increasing length anchored section when rock stratum embedded large enough. As behind increased, difference performances uniform increased gradually. research provide guidance evaluation service stability.
