n this paper we develop an approach for predicting the acceleration time history of ground motion on basic rock site using the theoretical seismology method. The acceleration time histories and response spectra in the Qinshan Nuclear Power Station are estimated. Four earthquakes with differnet properties and corresponding broad-band source models are designed depending upon the researches on the geology and the historic earthquakes in the studied region. Because the designing earthquake is a potential event occurring in the future, it can not be full determinant. Moreover there are the limitations of understanding the complex source process and the heterogeneity site structure. A synthetic method to combine both determinant and stochastic ways is studied. The ground motions are computed for specific source and medium models. The random disturbance quantity is introduced into the source parameters, and a statistical analysis for a large number of estimators is made.
