大体积混凝土裂缝成因与控制

Cause of Formation and Control of Mass Concrete Crack

近些年,国民经济、建筑技术发展迅速,建筑规模不断扩大,大型现代化技术设施或构筑物不断增多,大体积混凝土在构建大型设施或构筑物中的作用越来越重要。而大体积混凝土开裂则是工程建设中常见的技术问题,一旦出现裂缝,结构的耐久性就会降低,构件的承载力减弱,还可能对建筑物的安全使用带来威胁。因此,本文中笔者就运用有效的措施避免大体积混凝土的开裂进行了分析和研究。

In recent years,the national economy and construction technology developed rapid.The scale of building continues to expand.Large-scale modern technology facilities or structures are increasing.Mass concrete played a more and more important role in building large facilities or structures.And mass concrete cracking is common technical problem in engineering construction.Once appearing,it will reduce the durability of structures and weak the bearing capacity of construction member,may also threaten the safe use of building.Therefore,this paper studied how to avoid the cracks of mass concrete.
