                 軌道基座係為提供鋼軌扣件固結鋼軌的承拖系統,本文乃以板南線臺北車站以東採用鋼
            框模系統模板及土城線選用GSF模具比較兩種施築工法之特點,並就目前新蘆線所發展之軌
            道基座整體施工關鍵技術提出說明。

                 The track plinth is constructed so as to provide support for rail fasteners to clamp down the

            running rail. The aim of this article is to compare the construction characteristics of two construction
            methods. The first one is "the steel mold formwork" which is utilized on the section of the Nangang
            line east of Taipei Main Station; the other one is "GSF mold formwork" which is adopted on the

            Tucheng line. The article also depicts the development of key technology for the monolithic plinth
            construction on the Xin-Lu line.


            Keywords: bottom up method, top down method, baseplate bearing surface, refurbishing
