（中國建筑材料科學(xué)研究院 北京 100024）[提要] 介紹了以補償收縮混凝土為結(jié)構(gòu)材料、以加強帶取代后澆縫連續(xù)澆筑超長鋼筋混凝土結(jié)構(gòu)的設(shè)計施工方法。
[關(guān)鍵詞] U型混凝土膨脹劑 無縫設(shè)計 混凝土補償收縮原理The paper introduces a new design and construction method of eliminating back-filled joints for superlong reinforced concrete structure, and gives its theoretical basis and application results in engineerings. The method is initiative both in China and abroad, and concerns the design circle greatly.
Keywords: UEA; shrinkage-compensating concrete; jointless design; UEA expansive strengthening zone
