摘　　要：混凝土裂缝的控制是保证工程质量的关键。文章研究了混凝土裂缝的温度、干燥收缩、外力载荷等成因,介绍了传统与新型的混凝土裂缝控制技术,包括低热材料配比、分段施工、冷接缝设置、预应力化等。研究结果表明,合理采用低热混凝土、细分混凝土浇筑分段、预应力技术以及表面薄膜冷接缝等措施,可有效控制各类工程混凝土构件的裂缝。The control of concrete cracks is the key to ensure the quality of the project.This paper studies the causes of concrete cracks such as temperature,drying shrinkage and external force load,and introduces the traditional and new concrete crack control technologies,including low heat material ratio,sectional construction,cold joint setting,prestress,etc.The research results show that the reasonable use of low heat concrete,subdivision of concrete pouring sections,prestress technology and surface film cold joints and other measures can effectively control the cracks of various engineering concrete components.
