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．
Qinghua KG model was originally based on a three-axis test of damped rockfill proposed a soil constitutive model, weathering material is an important dam material, the particle composition and strength and deformation characteristics and rockfill and clay There is a big difference. According to the results of conventional triaxial tests of two weathering materials for the dam construction of the core of Henan Shuicheng Reservoir, the regression results of the model show that the model and the corresponding parameters can well simulate the deformation curves of weathering materials.
