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。

A two-dimensional mathematical model of flow and sediment is used to calculate and analyze the erosion of the riverway at Cao'e River Gate after its completed construction.

After operating the method of storing clear water and discharging muddy water in Sanmenxia Reservoir, the main reason for erosion and deposit in riverway is the change of running water level in flood season .

三门峡水库蓄清排浑运行以来，决定潼关以下库区河道冲淤主要是水库运行水位的高低，汛期水库运行水位的高低对潼关高程的升降起着主要的作用，因此汛期潼关高程的变化主要由水库运行水位决定的。

Due to their rapid growth and strong root system, they also help reduce soil erosion.

The lesion area in the vulva was washed with warm water to remove secretion on the ruga. If there was ulcer or erosion in the lesion area, the wound was washed with 3% hydrogen peroxide and normal saline. MEBO was applied locally to a thickness of 2 ~ 3 mm and bandaged in sterilized way. If there was no ulcer, MEBO gauze was applied to the vulva.

用温水清洁外阴皮肤及皱襞上的分泌物，如有破溃，糜烂面，再以3%过氧化氢清创，生理盐水清洗创面及周围皮肤，将MEBO涂于创面上，厚约2~3㎜，无菌包扎；非破溃创面，以MEBO制成药纱敷外阴，每次排尿、便后换药。

The results indicate the basic reasons of the soil erosion are plenty of discarding soil of cut slope and the increasing discarding soil by kinds of diseases of cut slope later not utilized by the embankment, moreover, the soil have to be borrowed to build the embankment, together with the ruleless of the places of borrowing soil and the fields of discarding soil.

结果表明，引起水土流失的根本原因在于路堑开挖的大量弃方，以及随后路堑边坡的各种病害造成新增膨胀土弃方不能为路堤施工所利用，而路堤填筑又需大量借土，加之借、弃土作业不规范等。

Based on the short gel-time features of ordinary cement sodium-silicate and alkali-activated salic cementitious materials, an ideal structure model of high performance sodium-silicate suspension two-shot grouting material was established. An experiment was undertaken to verify the solidification value of Na~+ and water-erosion resistance of a grouting material combined with cement and metakaolin-sodium silicate. This paper put forward a compact structure with a dominant ingredient of-Si-Al-H zeolite gel formed on later age and a minor part of C-S-H formed on early age, which composed of sodium-silicate, substances that could release Ca~(2+) spontaneously and stably or by the aid of sodium-silicate, and active salic substances.

结合普通水泥-水玻璃快速胶凝和碱激发硅铝质胶凝材料的特点，本文建立了高性能水玻璃悬浊型双液灌浆材料的理想结构模型，并通过水泥复合偏高岭土-水玻璃灌浆材料的Na~+固化性能和抗水溶蚀性能进行了试验验证，提出其组成结构应是以-Si-Al-H类沸石凝胶物质为主、C-S-H为辅的复合共存密实结构，其组成要素为水玻璃、能自发稳定地或在水玻璃作用下迅速释放出Ca~(2+)的物质、活性硅铝质材料。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
