新疆位于我国西部边陲,属于明显的温带大陆性气候,绝大部分地区冬季气温在零度以下,每年冬季都遇到渠床冻结发生冻害的问题,严重影响渠道运行安全。因此,在工程设计、施工和运行阶段,必须搞好防治冻害工作。针对新疆的冻害特点,依据有关规范和资料,本文阐述了渠道工程防冻胀设计中采取置换措施常见的几个问题。希望对类似的工程有参考意义。
Xinjiang is located in the western border of China. It belongs to the obvious temperate continental climate. In most areas, the temperature in winter is below zero. Every winter, Xinjiang has encountered the problem of frost damage on the canal bed freezing, seriously affecting the safe operation of the canal. Therefore, in engineering design, construction and operation stage, we must do a good job in prevention and treatment of frost damage. According to the frost damage characteristics of Xinjiang, according to the relevant norms and data, this article describes several common problems in displacement design of channel project frost heaving. Hope for similar projects have reference value.
