This study addressed the influence of the shear-wave velocity test standard deviation on ground motion.The Shake 2000 program and site model of Turkey Flat were used to analyze the response spectrum of ground and peak acceleration under a variety of engineering conditions by inputting different types of multi-intensity seismic waves.The study concluded the following:(1)the impact of the shear wave velocity test standard deviation on ground motion in the shallow stiff soil site is related to the intensity and frequency of the input seismic waves, and the calculated value of shear wave velocity;(2)if the response spectrum residuals or peak acceleration D-value exceed 20%, the effects of the velocity test standard deviation cannot be ignored in most situations;(3) when the predominant period of the input ground motion is similar to the characteristic site period, the changes of the response spectrum caused by the shear wave velocity test standard deviation in the shallow stiff soil site is significant;(4)only when the predominant period of the input ground motion with weak intensity and the characteristic site period are largely different, can the changes in the response spectrum caused by the test standard deviation be omitted;and (5)if the shear wave velocity in the shallow stiff soil is lower than the statistical mean value, the calculated value deviation of ground motion is larger than the measured value of shear wave velocity which is higher than the calculated mean value, and the ground response is more obvious with higher intensity of the input ground motion.
