摘要
研究土石材料的非线性、应力路径以及流变等对土石坝变形的影响，提出新的土石坝变形数学模型及迭代建模方法，算例分析表明新模型提高了拟合精度，研究工作使土石坝变形数学模型趋于合理。
?Through the study of the influence of non-linearity. stress path and creep of soil-rock on the deformation of earthrock dams. a new model and a method of model building are put forward. Practical examples. show that the precision and reasonableness of the new model are better than the old one.
