| 摘 要： | 饱和冻结黄土的抗拉强度与多种因素有关，其中应变率和温度是最主要的因素。本文在试验基础上，得到冻结黄土拉伸时的应力-应变关系曲线，进而分析了极限抗拉强度随应变率和温度变化的响应规律，并对上述响应规律给出了相应的拟会公式。

| Abstract: | The tensile strength of saturated frozenloess depends on a number of factors, among which the strain rate and temperature are of great significance.Based on experiments,the paper obtained the stress-strain relanonsof frozen loess under tensile tests.Moreover,the effects of strain rate and temperature on ultimate tensile strength were analyzed and the relevant equations were presented. |

| Keywords: | frozen loess tensile strength strain rate temperature |
