| Abstract: | Base on the analysis of the techniques commonly used in the process of maintenance and reinforcement of soil site,it is proposed that the anchored bolt and the masonry have much influence on the reliability of the structure.And the pseudo-cohesion theory is applied to the analysis of the reliability of the reinforced soil sites with anchor.Then,according to the Mohr-Coulomb failure criteria,Monte Carlo stochastic finite element method based on Latin hypercube sampling is applied to the analysis of stochasti... |
