At the same time the conclusion that the method of calculating the characteristicvalue of concrete fatigue strength using fatigue life agrees to that using initial strength is presented.
分析得到疲劳寿命概率分析方法和初始强度概率分析方法计算疲劳强度标准值具有一致性；

The density, hardness, bending strength, adhesive strength and ttibogy characteristic of the coating are measured in the test and the practical value is studied.
