摘要:
上游河道整治时，其治理宽度常涉及到沿岸土地取得的问题，使治理工作有时变得困难，最后只好依现况宽度或将宽度窄缩，以迁就现实。惟因溪流治理宽度直接影响溪流本身的排洪、导流及输砂等多项功能，如不能依照必要的溪流宽度及其相关配套措施予以整治时，对国土资源及人民生命财产或有不利之影响，故有必要加以探讨。据此，本文针对床砂粒径组成及来水来砂量等条件为已知的上游河道，在各种可能的治理宽度下，通过一定的理论推导及渠槽试验方式，建立溪流宽度及其相应的水深、溪床坡度及流速等水力要素间之河相关系式，并提出溪流治理宽度、护岸高度及基础深度等工程措施之设计模式，提供现场工程设计之参考。
Abstract:
Land ownership of floodplain is usually the major problem for upstream channel regulation such that design channel width is often forced to fit the current condition.However, regulating width of the channel also effects several functions of water resources such as flood sluicing,flow diversion and sediment transportation.A complete concept of channel regulation with appropriate channel width and auxiliary operations not only can have the conservation utiliy for natural resources but also can reduce the potential loss of human life and property. Hence,this study plans to structure the morphological relationships for related hydraulic factors(i.e.,channel width,corresponding flow depth,channel slope,and flow velocity) through theoretical inference and flume experiment under different combinations of grain size distribution of bed material and clear-water discharge in this year.With this relationship,design modelof construction operations for channel improvement width,dike height,and foundation depth can then be provided for the field operation.
