水工混凝土裂缝的出现和防治

摘要

混凝土裂缝普遍存在于水工建筑之中，裂缝出现会对混凝土建筑物的正常使用造成不同程度的影响，然而现阶段的水利工程技术尚不能完全解决此类问题。本文通过对裂缝理论上的成因和施工中造成裂缝出现的影响因素进行综合分析，提出设计上以及施工中对应的技术措施，减少裂缝出现，降低其对建筑物的危害。%Concrete cracks are prevalent in hydraulic structures,which can cause influence on normal use of concrete buildings at varying degrees.However,hydraulic engineering techniques cannot solve similar problems completely at present.In the paper,theoretical cause of cracks and influence factors causing cracks in construction are comprehensively analyzed,corresponding technical measures in design and construction are proposed,thereby reducing cracks and lowering its harm on buildings.
