The trailer body adopts reinforced type mudsill and is suitable for transportation on rugged road. With three BPW axles, 11.00R20 tyre, WABCO ABS brake and the load capacity of 13000 kg, the trailer is an ideal and safety choice for medium distance road transport of asphalt.

车体采用加强型结构底梁，适合坑凹不平道路的行驶要求，车轴BPW 3轴，负荷13000 kg，轮胎11.00R20，刹车WABCO ABS，是公路中程沥青运输、安全理想的选择。

The paper carries out mechanical analysis of the weight distributing of goods in loading container based on analysis of packing and tansporting environment, and draws the formula of the ratio of the weight of loading goods and the maximum loading weight W/W0, and the length distributing ratio of loading goods α=l/L under the condition that the bending quadrature produced by part load is within the range of the maximum bending quadrature. It also gives the graph that the sum deflection of mudsill and underside girder can reach high-point value with the length of bottom distributing varying, when the loading amounts of container of 20ft and 40ft are given. Furthermore, it provides the relation graph of an eccentric rate of loading goods and the allowed loading amount. For on-site safety loading work, it has certain guidance and reference value.

在分析包装件运输环境的基础上，对装载集装箱的货物重量分布进行了力学分析，得出局部负荷产生的弯矩如在最大容许弯矩范围以内时，装载货物重量与最大载货重量之比W/W0，同装载货物的长度分布率α=l/L的关系式；绘出了20 ft和40 ft集装箱在装货量一定时，随着货物底分布长度的变化，底梁和下侧梁之合计挠度达到极限值的曲线图；绘出了装载货物的偏心率与容许装货重量的关系图；对现场安全装载作业有一定的指导作用和参考价值。

The arch bending on the top of the original main arch ring corresponds to every arch rib and the bottom beam on its landscape orientation. As a result it becomes a down arc frame similar to slab-and-beam floor system. On the arch bending and bottom beam just established, standing pillar, main beam, horizontal rib beam and bridge front-panel would be built subsequently. Both ends of the main beam would then be put off the new hat beam made of reinforced concrete. Now, it becomes an upper slab-and-beam floor system. Two decks will be joined together on the middle of the bridge, which forms the ability of spanning and loading.

在原主拱圈拱肋相应位置处增设拱伏，横向增设底梁，形成一个下层弧形的类似肋梁楼盖的结构；在已浇筑好的拱伏与底梁上，继续现浇立柱、主梁和横向肋梁、桥面板，主梁的两端搁置在桥台处新增加的钢筋混凝土台帽梁上，形成一个上层肋梁楼盖结构，并且上下两层楼盖在桥梁跨中互为渗透结合成一个牢固的整体，共同完成了跨越和承载的能力。
