The characteristic curve ofaggregategrading may be described by the three parameters: maximum aggregate size, grading index and mineral filler content.
骨料级配曲线可用三个参数表征：骨料最大粒径、级配指数和填料用量。

It can get good effect through the measures of advancing the aggregategrading and increasing sand ratio and provide reference for similar engineering.
通过改善集料级配，适当增加砂率等措施来解决流沙问题能取得良好的效果，可为类似工程提供参考。
