碩士 === 朝陽科技大學 === 營建工程系碩士班 === 97 === In the recent years, Taiwanese government has promptly promoted infrastructural construction projects in many aspects necessary to uplift the overall competitiveness of the country. Among the major infrastructural projects, transportation networks constitute the most essential and dominant part of the constructions, especially in the major metropolitan areas where the transportation routes inevitably encounter difficult topography and man-made obstacles such as river, slope, rolling hill, existing railroad and highway,. etc.. In many cases, elevated pavement and/or bridges became necessary according to the site topography along the lines of the transportation network. The research collected and studied the important engineering elements of the commonly used bridge constructions in Taiwan and abroad, which include design concepts, construction procedures, and the characteristics, adoptability and criteria/limitation of the bridges. A selected bridge project in central Taiwan was also studied for comparison. Research was conducted with the emphasis of cast-in-place cantilever bridge which is commonly used for bridges of mid-span (35-60m) and long-span (60-120m) both in Taiwan and abroad. The contents of the study includes design concept and revealed critical automation and cycling of construction procedure for the 4 major construction types of the bridges: (1) advanced shoeing, (2) incremental launching, (3) cast-in-place cantilever, and (4) segmental advancement method. Among these, the cast-in-place cantilever which is the most used type in Taiwan, was studied to develop a list of advantage/shortcoming and improvement tactics to provide an useful guideline and reference for the deign and construction of the similar bridge construction projects in the future.
