| 摘 要： | 利用室内试验手段研究了不同备样方法对标准吸湿含水率的影响。研究结果表明：原状样和调制样的试验结果大于风干样和烘干样；原状样与其他3种备样方法的试验结果呈线性关系，相关系数的平方为0．94～0．97，说明在原状样缺乏时可采用其他备样方法的试验结果来代替，但必须对其进行修正。

| Abstract: | The testing result of standard absorption water content strongly depends on the initial moisture content, structural property, and moisture elimination and absorption procedure of the samples. It is important to study the standard absorption water content with different sampling methods. The research results show that the value of the undisturbed and remolded samples is greater than that of air-dried and oven-dried samples. A certain linear dependence relation exists between the standard absorption water content of the undisturbed sample and that of other three sampling methods, and the square of correlation coefficient is 0.94 - 0.97. After being modified, the testing results of other sampling methods can substitute for those of the undisturbed samples. |
