问答题 简答题
某一完全饱和粘性土试样的含水量为30%，土粒相对密度为2.73，液限为33%，塑限为17%，试求孔隙比、干密度和饱和密度，并按塑性指数和液性指数分别定出该粘性土的分类名称和软硬状态。
答案
参考答案：
因为10<IP=16<17,该粘性土应定名为粉质粘土；
因为0.75<IL=0.81<1.0,所以该粘性土的状态为软塑。

As my fingers played across the keys, I was becoming more 9 of my preparation for this moment. But the memory of my years of training came flooding back.
