谈灌砂法测定压实度的偏差

摘要

This paper analyzed the importance of sand filling method determination of compaction degree in highway engineering construction, from the standard sand quality,weighing apparatus,moisture content determination,test pit shape and other aspects introduced the factors influ-ence of sand filling method determination of compaction degree accuracy,and put forward the methods to improve the detection accuracy,provid-ed some suggestion for site inspection work.%分析了公路工程施工中灌砂法检测压实度的重要性，从标准砂的质量、称量器具、含水量测定、试坑形状等方面介绍了影响灌砂法测定压实度准确度的因素，并提出了提高检测精度的方法，为现场检测工作提供一些建议。
