The deficiency of present belt drives design criteria is pointed out to get a start in sliding failure and fatiguefracture failure.
从防止带传动打滑失效和疲劳断裂失效出发，指出现有带传动设计准则之不足。

Under the action of tensile stress and tensile stress, the bolt with relatively low strength will crack first, and then the fatiguefracture will occur.
在拉应力和应拉力交替的作用下，强度相对较低的螺栓会先产生裂纹，进而发生疲劳断裂。

The result indicates that fracture mechanics can be employed to forecast the fatigue life of the pavement on orthotropic steel bridge decks.
