| 摘 要： | 应用断裂力学理论，参照有关的测试方法，制作三点弯曲试样，对冻土的断裂韧度ＫＩＣ进行了实验测试，结果表明，含水量、温度及加载速度等是影响ＫＩＣ值的主要因素，通过对试验数据的分析处理，获得ＫＩＣ与主要因素之间的定量表达式。

| Abstract: | According to relevant testing methods, 3-point bending specimens are employed. Then we test and study the fracture toughness K_(IC) of frozen soil through experiment, using fracture mechanics theorys. From the experimental results, we learn that water content, temperature and loading rate are the main innuence factors on K_(IC) By analysing the experimental data, a quantitative experession between K_(IC) and main influence factors is obtained. |
