PDEM-Based Seismic Performance Assessment of Retaining Walls Considering Spatial Variability of Soil Properties
Spatial variability is a natural attribute of soil properties and strongly affects seismic performance of earth structures. A novel stochastic dynamics method, probability density evolution method (PDEM), is proposed for seismic performance evaluation of retaining walls considering spatial variability of soil properties. Abundant probabilistic results of retaining wall, such as the mean, standard variance, evolution of probability density functions and dynamic reliability, are acquired in present study. It is found that neglecting the spatial variability of soil properties by treating soil properties as a uniform field in each realization may overrate the safety of the retaining wall.
