Earthquake effect of the construction site in Shijiazhuang city was studied when the artificial wave is taken as input ground motion. The dynamic parameters in the model were taken from the measured values, recommended values in 94 Code and recommended values by X.M. Yuan respectively. The ground peak acceleration and acceleration response spectra are compared and analyzed, and it shows that the calculation results from the recommended values by X.M. Yuan are more close to the results from the real measured values than 94 Code. The results can be taken as a reference of the soil dynamic value in seismic risk assessment of engineering projects.
