Abstract
Hokuriku Shinkansen's Takasaki-Nagano section is 117 kilometer long and it will bring a new service between Tokyo and Nagano in one and half hour. This article, I introduces three characteristic concrete bridges in this section. On constructing Kirizumigawa bridge, a prestressed concrete strutted beam bridge, two technical methods were adopted to control the effect against the environment : the lowering erection method for the slant piers and the cantilever erection method for the main girder. Daini Chikumagawa bridge, the first cable-stayed prestressed concrete bridge in Shinkansen, set up the record of the longest span of the concrete railway bridges (133.9 meters). Yashiro Minami and Yashiro Kita bridges (main span : 105 and 90 meters each) are extradosed prestressed concrete bridges and this structural type can decrease the beam height of middle-sized concrete railway bridges.
