饱和粘土在循环荷载作用下的孔压预测

The Prediction of Pore Pressure of SaturatedClay under Cyclic loading

通过对饱和粘土循环试验成果的回归分析，建议了用两种模型分别描述ＮＣ粘土和ＯＣ粘土的循环加载孔压变化规律，并研究了在非等幅循环情况下（如波浪、风荷等不规则荷载）所建议模型的应用方法，本文所提供的模型比文献［１］所建议的“动孔压系数法”更符合粘土孔压的增长规律。

With the cyclic test results of saturated clay were analysed by regression, the authers give two models todescribe dynamic pore pressure development for NC and OC clays. These two models can be applied to nonuniform cyclic loading and accord with experiments more prefectly than reference .
