车辆荷载

Based on the coupled vibration theory, dynamic behavior of long-span steel bridge deck pavement under random moving vehicles was studied.

从耦合振动的角度出发，研究大跨径钢桥面铺装层在车辆随机动荷载作用下的响应机制。

There are great differences between the axle load used in the pavement design and the load moving at the actual pavement. The difference affects the degree of pavement damage due to axle load and the pavement life.

路面上实际行驶的车辆其荷载的大小与路面设计时所采用的理论值有一定的偏差，偏差的大小直接影响车辆对路面的损害程度和路面的使用寿命。

On the contrary, the maximum principal stress from the contact model is much bigger and morerational.

车辆在制动或起动过程中，轮胎会给路面很大的水平荷载。

According to research on space between wheel and Cart rut traverse curve of single roadway, the width of strip slab was fixed. When there was horizontal loading on slab, contact state between strip slab and base course was studied, and finite element model was established. Comparing maximum principle stress among different load position on slab, it was found that the critical loading position of cement concrete strips pavement was the middle of longitudinal joint.

对车辆轮距和单车道轮迹横向分布曲线进行分析，确定轮迹板板宽；在有水平荷载作用时，对轮迹板与基层的层间接触状态进行分析，建立有限元计算模型，对比荷载作用在轮迹板不同位置时的最大主应力，最终确定水泥混凝土轮迹路面板的临界荷位为纵缝边缘中部。

The traffic density, the load and moving speed increase day by day, which attract much attention on the interaction of the vehicles and bridges.

交通密度的日益增加、荷载的逐渐加重以及车速的不断提高，使得车辆与结构的动力相互作用问题越来越受到人们的重视。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
