摘要
系统地研究了场地地震反应分析中的不确定性及其产生的根源．利用蒙特卡洛法的有关理论，对影响场地地震反应分析结果的不确定性因素进行了估计与分析．实际应用结果表明，该方法是可行的。
The uncertainties from current site earthquake response analysis are analyzed and a method for solving the uncertainties of system parameters by using the Monte Carlo simulated method is presented.Some results using the proposed method are given and the effect of parameter uncertainties on reliability of earthquake response analysis is discussed.It is suggested that to estimate the input parameters by means of shochastic theory is necessary.It has been proved that the proposed method is advantageous both in computing efficiency and precision.
