The main works are as follows: 1 The developingt history of the traffic load on bridges is represented. Typical bridge codes in some countries are discussed and these traffic load models are comparative analyzed. Analysis shows that the influence of layout axle for the total traffic load effect on bridge gradually becomes smaller with the increase of bridge span. So most national norms use the distributed load as the equipollent load of traffic load.

主要内容包括下面几个方面： 1阐述了桥梁汽车荷载发展的简史，讨论了部分国家典型的桥梁汽车荷载设计规范，并对这些荷载模型进行了对比分析，分析表明随着桥跨的增大，车轴布置对桥梁整体荷载效应的影响逐渐变小，因而大部分国家的规范都把均布荷载作为车辆的等代荷载。

At the early iteratives, the mutation rate is bigger and the aim is to make particles to explore smaller and isolate region and to avoid the algorithm trapping to the local optimum. While the algorithm runs, the mutation rate will be decreased to reduce the disturbing to the particles. IPSO adopts a new method that congregates some neighboring individuals to form multiple sub-populations in order to lead particles to explore new search space. Additionally, our algorithm incorporates a mechanism with a simple and easy penalty function based on the largest distance between the particle and the boundary of the feasible region to handle constraint.

IPSO采用了一种新型的变异策略，变异概率随着算法的运行是动态变化的：在算法运行初期，变异概率大，其目的是使算法不但能够探测到目标空间中的孤立区域，而且避免搜索陷入局部极值；在算法运行后期，变异概率逐渐变小，以减少对粒子的扰动；算法通过将部分具有邻近距离的粒子聚集成核形成多子群引导种群中粒子的飞行；采用一个简单的基于粒子与可行域边界最远距离的罚函数处理约束的机制，使得算法高效实现。

The results show that the interplanar crystal spacing and lattice index of Al-rich α phase reduce gradually with increasing pressure. When the pressure reaches from common pressure to 5 GPa , Al-rich α phase lies on the (200) and (220) crystal faces, the interplanar crystal spacing are reduced by 1.07% and 1.15%. From common pressure to 3 GPa , the microstructure of ZA27 alloy changes from thick dendrites to fine dendrites, and finally to granular. According to the effect of solute diffusion coefficient under super high pressure and the calculation of Scherrer formula, it can be seen that the crystal organization is fine within the bounds of certain pressure. This conclusion is consistent with the experiment results.

结果表明：随着压力的增加，晶面间距和晶格常数都逐渐减小，当压力达到5 GPa时，富铝α相在(200)与(220)晶面处，晶面间距较常压力时的分别减小1.07%和1.15%；在常压至3 GPa范围内，晶粒由粗大的树枝晶→细小的树枝晶→粒状、椭球状枝晶转变的趋势，通过压力对合金凝固溶质扩散系数的影响结合Scherrer公式计算分析其组织变化原因，得出在一定的压力范围内，随着压力的增大，晶粒尺寸逐渐变小，这一结论与实验结果相符。
