对古水面板堆石坝玄武岩筑坝粗粒土堆石料进行了颗粒破碎试验。依据试验前后试样的颗粒级配曲线，研究了风化模型参数与颗粒破碎之间的关系。研究结果表明，风化模型能够很好地拟合试验前后土体的颗粒级配曲线，对于大粒径颗粒(大于5 mm)的级配拟合效果远优于分形几何模型；风化模型参数本质上反映了土体颗粒级配曲线与土体最大颗粒粒径线围成面积的大小及其分布状态；相对破碎参量Br 是风化模型参数的函数，可以直接通过试验前后土体颗粒级配曲线的风化模型参数求出。

The particle breakage tests were carried out to the basalt coarse granular soil of Gushui concrete face rockfill dam. The relationship between the parameters of weathering model and particle breakage was studied according to the grading curves of the soil before and after the tests. The study shows that the weathering model can well simulate the grading curves of the soil be-fore and after the tests, especially for the particle with large diameter (larger than 5mm), the simulation effect of weathering model is better than that of the fractal model. The weathering model parameter reflects the size and distribution of the area en-closed by the grading curve and the largest particle size curve. The relative breakage parameter of Br, a function of the parameter of the weathering model, can be directly calculated by using the weathering model parameters of the grading curves of the soil be-fore and after the tests.
