《有关桥梁的英语作文》
Bridges are among the most important, and often the most spectacular, of all civil engineering works.
There are six main types of bridges: beam bridges, cantilever bridges, arch bridges, suspension bridges, cable-stayed bridges and truss bridges.
A bridge is designed for trains, pedestrian or road traffic, a pipeline or waterway for water transport or barge traffic. An aqueduct is a bridge that carries water, resembling a viaduct, which is a bridge that connects points of equal height. A road-rail bridge carries both road and rail traffic.
Bridges may be classified by how the forces of tension, compression, bending, torsion and shear are distributed through their structure. Most bridges will employ all of the principal forces to some degree, but only a few will predominate. The separation of forces may be quite clear. In a suspension or cable-stayed span, the elements in tension are distinct in shape and placement. In other cases the forces may be distributed among a large number of members, as in a truss, or not clearly discernible to a casual observer as in a box beam. Bridges can also be classified by their lineage, which is shown as the vertical axis on the diagram to the right.
有以下比喻句可供参考:

扩展资料:
1、全分离式
全分离式立交桥是广义立交桥中最简单的一种,这种立交桥主要用于高架道路与一般道路、高快速路与一般道路、铁路与其他道路或铁路的立体交叉,其车辆通行方法极其简单,即各自在自己的线路上行驶。
2、半分离式
半分离式立交桥是一种简易立交桥,其特点是主干线上(一般为直行)的道路通过高架桥梁或下沉隧道与其他道路从原平面上分离,其余道路仍在原平面交汇。最大优点是结构简单从而实现最低的建设成本和难度,最大缺点是不能实现所有方向无障碍的快速互通。
3、半互通式
半互通式立交桥是一种介于全分离式和全互通式之间的立交桥,其特点是只实现部分道路方向的立交互通。比如在T字型立交桥中,支线的车辆只能汇入主线中的一个方向而不能转入主线的另一个方向。最大优点是因地制宜从而节约工程用地,最大缺点是无法实现全方向互通。
4、全互通式
全互通式立交桥是能实现所有方向(但不一定包括掉头方向)互相换行的立交桥,理论上能保证任何方向上的车辆无障碍通行。最大优点是可以实现全方位互通,最大缺点是结构复杂导致空间占用很大,且一经建成很难再进行改造。
