摘要： 含水率是土的重要物理性质指标，很大程度上决定土的力学性质。含水率测试方法较多,分别采用常用的烘干法和微波炉方法测试青藏红粘土的界限含水率,并对其结果进行了对比。结果表明：烘干法和微波法所测得数据基本吻合，而计算所得的塑性指数，烘干法和微波法都在相同的范围之内。所以，对于青藏红粘土而言，烘干法和微波法是可以相互替代的。

Abstract: The moisture content is an important property of soils and is an index of mechanical property. The moisture content can be determined by various different methods. Of many testing methods, this paper presents the comparative test results on the moisture contents of red clay samples from QinghaiTibet with oven dry as well as microwave dry methods. The test results indicate that the moisture contents tested by oven dry and microwave dry are similar. The plastic indices obtained by both methods are also similar. For the QinghaiTibet red clay, the moisture contents by oven and microwave method can be substituted.
