| 摘 要： | 概述了影响大体积混凝土抗裂性的因素，确定了大体积混凝土抗裂性指标评估数学模型，建立了混凝土配合比设计和抗裂指标的关系，编制了我国第一大体积混凝土抗裂配合比优化设计程序。该程序可根据设计要求和原材料设计出抗裂性能较优的大体积混土配合比，也可以对已知混凝土配合比进行抗裂性能的评估，从而节省大量的人力、物力和财力，缩短设计周期，带来较大的经济效益。

| Abstract: | The factors effecting mass concrete crack resistance are described,the mathematic model appraising mass concrete crack resistance indices is set up,the relation between concrete mix proportion design and crack resistance indices established and the design program optimizing mass concrete crack resistance mix proportion worked out.The program may design a mass concrete mix proportion with better crack resistance behaviour in accordance with design requirement and ufilized raw materials and qppraise the crack resistance for known concrete mix proportion. |
