摘要
基于邓肯E-B模型运用总应力法和有效应力法对某水库围堤进行有限元应力变形计算分析,对比两种计算方法的计算结果。以掌握两种计算方法在围堤有限元计算分析中差异。计算结果表明:总应力法与有效应力法的计算结果规律基本一致,总应力法计算的大、小主应力值比有效应力法计算值要大些,有效应力法计算的围堤沉降位移比总应力法计算的要小,但水平向位移有效应力法计算的比总应力法计算的要大,有效应力法计算结果更能真实地反映了土体的实际变形情况。
The stress and deformation of a reservoir embankment are calculated using FEM based on the total stress method and effective stress method. The comparison of calculation results based two kinds of calculation methods is conducted to show the difference between the two kinds of methods. The results show that the rules of the results of total stress method and effective stress method are the same.But the stress of total stress method is bigger than that of effective stress method. The settlement displacement of effective stress method is less than the total stress method. But the horizontal displacement of effective stress method is bigger than that of total stress method.The effective stress method is more realistic to reflect the actual deformation of the soil.
