Stochastic nonlinear ground response analysis considering existing boreholes locations by the geostatistical method

The field and laboratory evidence of nonlinear soil behaviour, even at small strains, emphasizes the importance employing methods in seismic ground response analysis. Additionally, determination dynamic characteristics layers always includes some degree uncertainty. Most previous stochastic studies analysis have focused only on variability parameters, effect sample location has been mostly ignored. This study attempts to couple time-domain with parameters considering existing boreholes’ through a geostatistical method using program written MATLAB. To evaluate efficiency proposed method, responses construction were compared those non-stationary random real site data. results demonstrate that applying significantly affects not but also their coefficient variation (COV). Furthermore, mean value is affected more considerably by values vicinity location. It inferred may reduce COV responses. Among surface studied site, peak displacement (PGD) acceleration (PGA) reflect highest lowest dispersion due properties both methods.
