提出一种近似考虑固结程度的总应力法算法,其计算参数通过非饱和心墙料的固结不排水试验确定。该总应力法可以近似计算出固结变形,从机制上更接近实际。通过双江口堆石坝掺砾黏土心墙试验与计算,并与现有的总应力法计算结果比较,验证该总应力法算法的可行性。
A new total stress method and test method are presented to simulate consolidation degree of core in rock-fill dams.And its model parameters can be achieved by consolidated undrained compressibility test.The consolidation deformation can be calculated by new method.The superiority of new method is confirmed by model parameters test and stress-strain calculation for Shuangjiangkou dam.
