| 摘 要： | 通过对贵州一些中型水利水电工程中风化料试验资料的对比分析，认为与一般常用的红粘土比较，前者具有宽级配之属性，不均匀系数大，最优含水量与天然含水量相近，易于施工碾压，抗剪强度高，压缩性能好；只要控制区实后粗颗粒（ｄ＞５ｍｍ的颗粒）含量适当便能获得满意的防渗效果，可作为良好的防渗材料。

| Abstract: | Analyzing the data of preliminary test on moderately weathering materials of some medium-size water conservancy projects in Guizhou province,the writer considers that the weathering materials have wider graduation attribute, bigger non-homogeneous coefficient and the best moisture content more similar to natural one,higher resistance to shear,better compressibility and are easiler for roller compaction in comparison with red clay usually used. They,therefore,can be used as good antiseepage materials provided coarse pellet (d >5 mm) content after roller compaction is suitable. |
