对不同结构类型的水泥稳定类试件进行试验室三分点加载弯曲疲劳试验,通过不同级配类型的强度数值来拟定疲劳试验的荷载中值,并测出对应的荷载作用次数,从而确定试件的抗疲劳能力,试验数据得出,骨架密实型的疲劳性能优于悬浮密实型,其中又以级配一的抗疲劳性能最优.
對不同結構類型的水泥穩定類試件進行試驗室三分點加載彎麯疲勞試驗,通過不同級配類型的彊度數值來擬定疲勞試驗的荷載中值,併測齣對應的荷載作用次數,從而確定試件的抗疲勞能力,試驗數據得齣,骨架密實型的疲勞性能優于懸浮密實型,其中又以級配一的抗疲勞性能最優.

Based on experimental of three-point-bending fatigue loading test indoors on stable cement testpieces of different structural types,this article maps out the load value of fatigue tests through the analysis on different types of intensity values,and it measures the correspondent load times,so as to define the anti-fatigue capacity of the test -pieces. Experimental date reveal that the anti-fatigue capacity of denseframe tesl-pieces is better than that of the suspension close-grained type, and level 1 has the best performancc.
