When Sinlaku hit Taiwan during September 12-15, 2008, the extremely torrential rain made Hou-Fong Bridge, located in downstream of Shi-Gang Dam, broken at around 6:50 p.m. on September 14, 2008. In this study, the case was applied to investigate the factors which resulted in the typhoon flood scour disaster and the disaster prevention mechanism, including the general scour of upstream and downstream river banks, the riverhead erosion and constriction scour, the free fall of broad-crested weir effect caused by water-pipe protection engineering, the disaster prevention and response of the bridge care and management unit, and the examination, timing and procedure of bridge block.

中文摘要本研究系以97年9月12日至15日强烈台风辛乐克侵袭台湾期间，所降下的超大豪雨造成位在大甲溪石冈坝下游后丰大桥於9月14日下午6点50分左右发生断桥事件为例，探讨台洪冲刷灾害成因与防灾应变机制，包含上下游河道之一般冲刷、河道向源侵蚀与束缩冲刷及位於桥梁上游约20公尺处之自来水干管保护工所产生宽顶堰跌水效应等影响，并检讨桥梁养护管理单位於断桥发生前防灾应变处置方式及台洪期间之巡查检测、封桥时机与封桥作业流程等等相关因应作为。

In the region upstream of vortex breakdown, the sectional streamlines emanating from the leading edge spiral inward to primary vortex and in the region downstream of the breakdown, on the other hand, the streamlines separating from the leading edge are not entrained into the vortex core in the instantaneous sense. Along the axis, the topology of the primary vortex alters several times starting from stable focus near the apex to unstable focus, and lasts back to stable focus near wake edge, the stable hmit cycle and unstable limit cycle are shown in this evolution.

发现在截面流线谱中，即使奇点的类型、数目及位置相同，奇点的连接方式也有可能不同；旋涡破裂点前，主涡由来自前缘的力线卷绕而成，主涡焦点与前缘半鞍点相连，旋涡破裂后，来自前缘的力线不再卷入主涡，主涡焦点与对称面上的鞍点相连：在流体由翼尖流向后缘的过程中，截面流线谱的拓扑结构发生了多次变化，主涡焦点相继由稳定状态转变为不稳定状态，最后又转化为稳定状态，并先后出现了稳定的极限环及不稳定极限环。
