代表材料的内部状态的引申的损坏根据连续媒介的力学的理论被介绍给具体力量理论;败坏的水泥的失败标准是 disccussions。在测试,超声的速度被用来建立损坏变量;在结冰融化下面建立水泥的联合损坏的失败标准。结果证明失败表面逐渐地随结冰融化时间的增加正在缩小。而且,由在理论数据之间的比较;从文学的严峻的数据,力量理论的合理性在纸求婚了获得证实。这里介绍的联合损坏的失败标准能在水泥的失败表面上显示损坏进化的影响。
The damage which represents the alternation of internal slate of material was introduced to concrete strength theory according to the theory of mechanics of continuous medium and the failure criterion of deteriorated concrete was diseussions. In the tests, ultrasonic velocity is used to establish the damage variable and to establish the damage-eoupled failure criterion of concrete under freeze-thaw. The results show that the failure surface is gradually shrinking with the increase of freeze-thaw times. Furthermore, by the comparison between the theoretical data and the testing data from the literature, the rationality of strength theory proposed in the paper acquire confirmation. The damage-coupled failure criterion presented here can indicate the influence of damage evolution on the failure surface of concrete.
