The chief achievements are as follows: The dissertation studys the application of bowl scaffold bracing system in the bridge construction, and summarizes the reasons of falsework collapse.

主要研究成果如下： 对碗扣式支架系统在桥梁施工过程中的应用做了研究，总结了支架支撑倒塌的原因。

Certain portion of the bridge would be as high as 11-floor building, and there would also be a section of 75-meter-long cantilever on the bridge with no bracing in front of it.

这个桥的某些部分有整整11层楼高，桥上还包括一段伸出75米的悬臂，前端没有任何支撑。

The numerical results show that the travelling wave effect has significant influence on the long span arch bridge, the arrangement of bracing beams is sensitive to stability.

分析表明，地震行波作用对大跨径拱桥影响很大，横撑设置对稳定性敏感。
