The shaker mount is first moved a small distance toward the arch ends to ensure that the arch possesses two stable equilibrium positions, one on each side of the base line. The spring connecting the arch end and the mechanical shaker is carefully chosen such that small shaker stroke can induce large vibration amplitude of the arch.

此外，我们在激振器与拱形梁之间外加一个弹簧做连接，这可使激振器在仅能达到有限的激振振幅下，仍能使拱形梁端点有足够大的振幅产生，并使之能够发生折断式挫曲现象。

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。
