| 摘 要： | 本文提出当前大中型刚性衬砌渠道在寒区环境冻融条件下,出现的普遍和严重破坏,是由于冻胀变形、融沉变形、潜在不稳定渠道在渗透力作用下的变形以及脉动水流、温度应力产生的变形等综合作用形成的最大破坏效应的结果。文中并提出解决这种综合效应破坏所应采取的治理方法。

| Abstract: | This paper proposed that the serious wreck of the rigid channel revetment on freeze-thaw condition in frigid region be due to the result of maximum destructire effect caused by the comprehensive action that is freexing and dilatating deformation, thawing and wetting deformation, the deformation resulted from seepage force against latent unstable channel base as well as the deformation caused by temperature stress of fluctuating flow and so on. Moreover,it is proposed that the adoptable means may solve the synthetical destruction effect. |
