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。

It has a high activated alkali degree,strong PH buffering effect,and strong resediment effect.It cooperates with suface activated agent well. Its aid-washing effect and detersive power in scour is almost the same with that of STPP,so it can replace STPP.It is an excellent new silicate non-phosphor washing assistants.It can be used to produce washing power in both front and back compound product line.It is also an imporant washing assistant for paste and liquid washing as well as basic raw material for industrial scour.It has wider foreground in market.

层状结晶硅酸钠具有较强的软化水和去污能力，很好的活性碱度，PH缓冲能力和抗再沉积能力强，与表面活性剂有较好的协同作用，用在洗涤剂中的助洗效果和去污能力与三聚磷酸钠相近，是优秀的新型硅酸盐助剂，可用于前后配料生产洗衣粉，也是膏状、液体洗涤剂的重要助洗剂及工业清洗剂的基础原料，产品市场前景广阔。

The result shows that the erosion presents as incision when the riverbed is relative narrow and deep; To the low-water branching reach with strong boundary conditions where the riverbed is wide and shallow, the scour and deposit variation characteristics mainly presents as erosion and deposition adjustment of river island, height deviation of thalweg in the inlets and the adjustment of split ratio after impoundment To the low-water branching reach where the riverbed is wide and shallow and the lateral boundary conditions are weak, the scour and deposit variation characteristics is not restricted to the adjustment of split ratio, and the pattern of the braided reach may even be changed.

结果表明：当河段相对窄深时，河段冲刷主要为下切；当河段为相对宽浅的低水分汊河段且河岸约束较强时，蓄水以后的冲淤变化主要体现为江心洲滩的冲淤调整、汊道深泓高程差的冲淤调整，并引起主支汊分流比的调整；当河段为较为宽浅的低水分汊河段且河岸约束相对较弱时，则冲刷调整不仅限于分流比的调整，甚至会导致大的分汊格局的调整。
