桥头

Bridge approach settlement criterion is an important issue in solving Bridge bump, but there is not a reasonable criterion of theory in the world.

桥头引道沉降控制标准的问题是解决桥头跳车的一个重要问题，但目前国内外还没有一个理论上较为合理的标准。

With the help of Marc program, through simulating the foundation condition and loose area under the flexible approach slab, the changed rule of stress and displacement was analyzed, the active mechanics of the flexible approach slab in dealing with the jump was discussed.

运用Marc软件，通过模拟地基沉降和桥头脱空区，仿真分析路堤应力和位移的变化规律，研究了楔形柔性搭板处治桥头跳车的作用性状。

Do not cross the bridge till you come to it.

车到山前必有路,船到桥头自会直.
