如何准确用灌砂法测定路基的压实度

How to Measure the Compactness of the Roadbed by Using the Sand-pouring Method Accurately

简述了灌砂法的基本原理,从试验前的砂的标定、现场检测和最大干密度3个方面具体分析了影响试验精度的因素。

This paper briefly introduces the basic principle of the sand-pouring method, and makes concrete analysis on the factors influencing the precision of the test from three aspects of the standardization of the sand before the test, the field inspection and the maximum dry density.
