对某电站大体积混凝土裂缝的成因进行了探讨,通过分析得出：该大体积混凝土裂缝为温度收缩裂缝,其形成主要与温度变化量,混凝土厚度及外部约束作用有关,为今后类似大体积混凝土裂缝的防治提供了参考。%This paper discussed the cracks reason of mass concrete of a power station,through the analysis： the mass concrete crack was temperature shrinkage crack,its formation was mainly related to temperature change,concrete thickness and external constraint,provided reference for the future similar mass concrete crack control.
