摘要
本文系统地分析了水工混凝土在施工过程中常见的干缩裂缝 ,温度裂缝 ,冷缝等的成因及危害 。
It is known that the concrete crack of hydraulic structure is divided into the crack which occurred during construction and the crack which occurred after completion of the construction.The former includes feather crack,contraction crack,surface crack,crack due to bleeding,crack due to formwork deformation,crack due to settlement and vibration of foundation,and cold crack.The latter has temperature crack,structure crack,crack due to reinforcement corrosion,crack due to low grade of concrete,and crack due to alkaline expansion of concrete.In this paper,combined with the concrete crack occurred in the hydraulic engineering at home,the genesis,characteristics,and harm of it to the hydraulic structure are illustrated.The treatment measures including the preparation work,material selection,and several methods for patching concrete crack,together with prevention measures are introduced.
