摘要
制备了四点弯曲试样并制作了相应的四点弯曲实验装置,进行冻土断裂韧度K_(ⅡC)的测试研究,测定了冻土K_(ⅡC)的值,获得了K_(ⅡC)与含水量、温度及加载速率的关系。
Four-point bending tests were conducted on frozen soil at various testing conditions so as to determine its fracture toughness KIIC. The test results show that the values of KIIC of frozen silt increase with lowering temperature and increasing water content, and are not sensitive to loading rate.
