| 摘 要： | 假定地震过程为零均值平稳高斯过程，土料的非线性特性符合Ｈａｒｄｉｎ－ Ｄｒｎｅｖｉｃｈ双曲线模型，将地震砂土液化过程模拟为随机荷载作用下的累积损伤过程， 建议了分析砂土液化的概率方法。应用这一方法，对日本新泻地震砂土液化实例进 行了广泛检验．所得结果与实际震害现象符合良好，表明本文方法简便实用，结果可 靠，为更合理地进行砂土液化分析提供了一条新的途径。

| Abstract: | in this paper, the earthquake process is assumed to be stationary Gaussian process, and the nonlinear dynamic property of sands is described by Hardin-Drnevich hyperbolic model. The process of seismic liquefaction to sands is simulated as a fatigue failure process under a stochastic loading. A probabilistic method analyzing liquefaction is proposed. The results obtained from analysis of Niigata Earthquake confirm the applicability of the method. |
