Abstract

Abstract

In order to scientifically evaluate the time-dependent stability of anchored soil slopes， a time-dependent reliability analysis model for slopes was established based on the coupling model between anchorage prestress loss and soil creep， considering the spatiotemporal characteristics of soil strength parameters and the time-dependent characteristics of anchorage force. Furthermore， Monte Carlo simulation was used to calculate the failure probability of anchored soil slopes and determine the corresponding reliability index values. The research results indicated that the established reliability analysis model revealed the time-dependent and stochastic characteristics of parameters for the anchored slope. In addition， the case analysis not only verified the rationality of the model calculation results based on Monte Carlo simulation， but also demonstrated the practical applicability of the time-dependent reliability analysis model in engineering practice. In summary， the established time-dependent reliability analysis model can be used for the design and stability assessment of anchored soil slopes， providing scientific basis and technical support for their safety management during operation.
