桥梁工程中大体积混凝土裂缝的原因与控制

Reasons and control of mass concrete crack in the bridge project

从水泥水化热的影响、混凝土的收缩、外界气温变化的影响三方面分析了桥梁工程中大体积混凝土裂缝的原因，从大体积混凝土的骨料选择、设计、施工等方面介绍了其裂缝的控制措施，防止危害裂缝的产生。

It analyzes the generating reasons of mass concrete crack in the bridge project from the aspects of cement heat of hydration influence, concrete contraction and external air temperature change. Then it introduces the crack control measures from the skeletal material selection, design, construction etc of mass concrete so as to prevent the generation of damage to crack.
