| 摘 要： | 我国北方冻害地区的渠道防渗工程由于冻害使其寿命缩短、效益降低、甚至造成滑塌等事故,损失严重。本文从分析土的冻胀机理着手,重点从力学角度认识U形断面的结构特点,并通过大量试验和实际应用表明U形断面在抵抗冻胀力方面优于其他断面形式。

| Abstract: | Because of the freezing damage,the life of the seepage-control works of canals in the north of China is shortened,the benefit of them is lowered,and even the sliding failure to them is caused.In this paper,firstly,the mechanism of frost heave is analyzed;secondly,the frame character of U-shaped section is recognized at the aspect of mechanics;thirdly,the U-shaped section is proved to be better than other shapes after a lot of experiments and practical applications. |
