In order to evaluate the sediment capacity and the stability of the Danshui river mouth, the proper evaluation of sediment transport in this region is required. In this study, we will explore the bedforms around Danshui river mouth and the evolution of Waziwei sand spit and aeolian process in an one-year span. The hydraulic data will be continuously collected , and will be used to calibrate the suitable sediment transport equation. The model will be evaluated by either experimental or field studies. The goal of this study is to provide some alternatives to resolve the sediment erosion and accretion problems around Danshui river mouth and the Taipei Harbor.;研究期間：10403~10412 <br> Fri, 11 Sep 2015 07:10:01 GMT https://ir.lib.ncu.edu.tw/handle/987654321/61877 title: 103年淡水河下游及河口附近水理輸砂及地形變遷研究;Sediment transport and geomorphological evolution around Danshui Rivermouth abstract: 研究期間：10303~10312;The mechanisms controlling the sediment transport around Danshui river mouth and the surrounding coastalines are tides, waves, river flow, suspended load and bed load.

Recycled materials, which had been properly treated and qualified, could be applied to various kinds of domestic civil engineering constructions, according to their characteristics, then we can achieve the purpose of fully driving the regeneration of waste materials. The need and quality demand of our transportation systems had increased year by year due to Taiwan’s rapid economic growth. Therefore, the demand of raw materials for pavement engineering increases enormously. Thus, the exploitation of natural sandstones as raw materials in Taiwan is facing the bottleneck of supply shortage. As to promote the construction of public facilities that could give consideration both on environmental protection and sustainable use of natural resources, this research aims at the pavement construction, and divides it into four phases. First from collecting data to laboratorial tests, then from on-site pavement to practical applications, and gradually we proceed various types of cost-effective evaluation of recycled materials. With the cost-benefit analysis of both the classification of recycled materials and treatment technologies, plus the understanding of the recycled materials’ economical and environmental benefits, we can speed up the raise of the proportion of reuse and recycle in our country. At last, we confer on laboratorial-designed cases with the possibility of general applications of recycled materials on future constructions. Meanwhile, establishing “The standard outlines for utilization the recycled materials on Pavement Engineering”, and “The manual handbooks for utilization recycled materials on Pavement Engineering” will be achieve during research period. ; 研究期間 9702 ~ 9712 <br> Mon, 01 Oct 2012 03:06:04 GMT https://ir.lib.ncu.edu.tw/handle/987654321/55067 title: 強化公路鋪面品質整合型計畫－道路養護品質知識管理之研究;Integral study of improving pavement quality in highway：study of road maintenance quality with knowledge management. abstract: 我國在經濟發展下，國民生活水準日益提升，對於生活品質要求越來越高。公路身為人民行之必須建設，品質亦須有所提升。在相關法規及規範日益健全的今日，公路主管單位日漸遵循一套機制運作，雖符合標準作業流程的精神，但對於偶發異常事件卻難以在整體統計資料中發現，對於人員的學習和經驗亦無法傳承，如此在過去依某些經驗所掩蓋的問題將顯現出來。故本研究以將更新及修正現行鋪面養護管理系統，建構模組分為以活動為基礎之成本分析模組、連續時間預測模組、離散事件預測模組、一般統計分析模組、時空分布分析模組，透過導入知識管理於養護作業中，並進行系統推廣及尋找示範工務段共同進行系統修正，蒐集相關成效資料，以實例驗證，達成以減輕基層工程師工作負擔之目標。 ; Because economic development is growing, the national living standard improves day by day; people require higher and higher the quality of the life. The road is one of the most important infrastructures, the quality must be improvement too. The regulation and norm have been all already sound now, the responsible institution of the highway has followed a set of mechanisms operation gradually. Although accord with the spirit of the procedure of the standard homework, it is difficult to find the accidental unusual incident in the whole statistical data. It is also unable passing study and experience on. This study will renew and revising the current pavement management system, we will build cost analysis model with Activity-Based Cost, continuous time prediction model, dispersed incident predict model, general statistical analysis model, and distribution of space-time analysis model, through put knowledge management into maintenance work. Carry on system popularize and system revising, and collect related performance data to verify the instance, in order to lighten the basic engineer’s work burden. ; 研究期間 9703 ~ 9711 <br> Mon, 01 Oct 2012 03:06:03 GMT
