回填材料含水率检测美标与国标方法对比研究

由于地基的稳定性对上层建筑的影响非常大,所以无论是路基路面,还是厂区回填,压实度的检测至关重要,而压实度又与回填材料的最大干密度、湿密度、含水率有关,其中湿密度和含水率必须根据现场的取样得出.针对回填材料的含水率检测,国内常用的方法是烘干法,国外常用的方法是快速含水率检测法.两种方法都可以检测回填材料的含水率,也各有优缺点.现针对两种检测方法进行了试验结果分析对比研究,所得结论可供有关方参考.
Comparative Study of American and Chinese Code Methods for Determining the Moisture Content of Backfill Materials
The degree of compaction testing is critical for both the roadway subgrade and the factory backfills since the stability of the foundation soils has a significant impact on the superstructure.The compactness is closely related to the maximum dry density,the wet density and the moisture content of backfill materials,among which the wet density and moisture content are obtained based on the on-site sampling.For moisture content determination of backfill materials,oven dry method is commonly used in China,and the rapid moisture content determination method is usually allowed abroad.Both two methods can determine the moisture content of backfill materials,and each has its own advantages and disadvantages.This paper analyzes and com-pares the test results of both methods.
