摘要：

摘要：经典土力学的理论基础是水土两相饱和，三轴试验中的试样要求达到饱和。针对粉土自身遇水易扰动的结构特性，作者通过对邯郸地区的粉土试样采用反压饱和的方法使试样饱和，取得了较为理想的饱和效果，分析得出针对邯郸地区粉土较为合理的反压参数，为粉土试样饱和试验提供参考。

Abstract:

Abstract: The basic theory of classical soil mechanics is based on saturated Water-Soil Two-Phase, and the sample of the three triaxial tests is required to be saturated. Aimed at the structure characteristics of silt that it is easily to be disturbed with water, the author makes the sample saturated with the method of back pressure and achieves ideal results. Meanwhile, the reasonable parameter of back pressure is obtained, focusing on the silt in Handan. It provides some references for silt samples saturated tests.
