水利工程是基础产业工程,但是水工混凝土却经常受到裂缝、冻胀、冲磨、空蚀、等病害的威胁,增加了水工建筑物使用过程中的修理与加固费用,影响或限制了结构的正常使用功能并缩短结构的使用年限,影响效益和安全,不仅造成经济损失,而且严重浪费资源,引发社会问题。本文对混凝土水工建筑物发生的通病进行了归纳阐述,针对不同的病害提出了防治措施。
Water conservancy projects are basic industrial projects, however, hydraulic concrete is often threatened by diseases such as cracks, frost heaving, erosion, cavitation erosion and the like, which increases the cost of repairing and reinforcing the hydraulic structures in use and affects or limits the structure The normal use of function and shorten the structure of the service life, affect the efficiency and safety, not only cause economic losses, but also a serious waste of resources, triggering social problems. This article summarizes the common problems occurred in concrete hydraulic structures, and puts forward some prevention and control measures according to different diseases.
