清华K-G模型对筑坝用风化料的适应性研究

清华K-G模型最初主要是基于筑坝堆石料三轴试验提出的一种土体本构模型，风化料是一种重要的筑坝材料，其颗粒组成与强度和变形特性与堆石料和粘性土都有较大的不同．针对云南水城水库心墙堆石坝筑坝用的两种风化料的常规三轴试验结果用该模型回归参数，结果表明该模型及相应参数能较好地模拟风化料的变形试验曲线．

Fitness of Tsing Hua K-G Model to Weathered Soils of Earth Dam

Tsing Hua K-G model is a stress-strain model of soils proposed mainly based on three-axial test of rock-fill soils; weathered soils are very important dam construction materials, and their grain contribution and mechanic proprieties are different from rock-fill materials or cohesive soils. Model parameters of several soils of Shui-Cheng reservoir is regressed from conventlonal three-axial tests. The fitness of the model to soils of earth dam is demonstrated by imitating test curves using the model.
