1·The permissible stress range formula and transfer factor of fatigue stress range were deduced.

推导了疲劳许用应力范围计算公式和不同概率水平下疲劳应力的转换关系。

2·It is suggested that the load form should be designed by using permissible stress method and the calculation of deformation is carried out in this paper.

我们采用许用应力法设计，后计算变形，再用垫尖起拱抵消浇筑变形，并配套有效地控制裂缝的浇筑方法。

3·Main conclusions: the wave-proof plate is safe when the permissible stress of the selected material is greater than the maximum calculated stress's 3.5 times of it.

主要结论：所选材料的许用应力大于通过该种方式计算得到的该防浪板的最大应力的3.5倍时，该防浪板是安全的。

4·The results show that stress in hollow beam and semi-shaft bush is much less than permissible stress, while joint of suspension frame and axle housing has too large local stress.

结果表明，驱动桥壳空心梁和半轴套管部分的应力远小于材料的许用应力，而悬架支座与桥壳连接处出现了局部应力过大的情况。

5·The system will also withstand a single maximum 100-year wave height of above 30m with stress levels below 60% of permissible and with small maximum accelerations.

除此之外，该系统可以承受一次百年一遇的大浪，承受超过30米的浪高、不高于60%的压力许可值以及小范围的最大加速度。
