我国新疆气候寒冷,冬季与水接触的建筑物常因冻胀作用而遭到破坏。如土坝上游护坡常因拔或冰推而破坏;混凝土建筑物的迎水面水位变化区常因冻融而破坏,表现为混凝土表面酥松剥落、强度降低;渠系建筑物的柱基甚至会被冻胀拔起。如不及时进行修补,则会影响建筑物的安全运行。本文论述了水工建筑物冰冻破坏的原因及破坏的形式,探讨了如何进行防治的措施。 In our country, the weather in Xinjiang is cold and the buildings in contact with water in winter are often damaged by frost heaving. For example, the upper slope of earth dam often is damaged by pulling or pushing ice; the changing area of ​​water level of concrete buildings is often destroyed by freeze-thaw, which is manifested as crisp and spalling of concrete surface and lower strength; Heave swelling up. If not repaired in time, it will affect the safe operation of the building. This article discusses the causes of the freezing damage of hydraulic structures and the forms of destruction, and discusses how to control the measures.
