摘要
为提升水利工程建设水平,切实发挥水利工程的作用,施工单位需格外重视水利工程中混凝土裂缝的防治工作.文章分析了水利工程施工中混凝土裂缝产生的主要原因,包括不均匀沉降、塑性收缩、干燥收缩、温度影像和自生收缩,针对这些常见裂缝,重点阐述了混凝土裂缝控制策略,在工程现场采取优化材料性能、控制工艺过程、优化构造设计、修补裂缝等技术措施,以有效预防混凝土开裂问题,提高水利工程的抗渗性能,延长其运行寿命.
Abstract
In order to improve the construction level of water conservancy engineering and give full play to its role,construction units should pay special attention to the prevention and control of concrete cracks in water conservancy engineering.This paper analyzes the main causes of concrete cracks in the construction of water conservancy engineering,including uneven settlement,plastic shrinkage,dry shrinkage,temperature imaging and autogenous shrinkage.In view of these common cracks,the control strategy of concrete cracks is emphatically expounded.on the engineering site,technical measures such as optimizing material performance,controlling process,optimizing structural design and repairing cracks can be adopted to effectively prevent concrete cracking,improve the impermeability performance of water conservancy engineering and prolong their operating life.
