The temperature, strain, stress etc. of each construction method are examined to improve the process of quality improvement. By applying the equation of three dimensional thermal and stress coupling analysis, this study examined potential for and control of the cracks in concrete structures in the regions, especially in a three dimensional short span of the structure. Relieving restraints on the existing base concrete by a retarder concrete layer, the effects of crack prevention of a crack were better than with either fiber concrete and reinforcing ku concrete. It is necessary to examine the mix proportion suitable for each construction method, because the consistency of the concrete will differ by the construction method.}, pages = {1--7}, title = {寒冷地のコンクリート構造物の高品質化のための3次元温度応力解析をもちいた各種施工の研究}, volume = {32}, year = {2001} }
