| 摘 要： | 通过对砼衬砌梯形渠道的冻胀破坏特征和机理的探讨,对渠道衬砌结构及其所受荷载进行简化,并分析其受力情况.认为梯形渠道边坡板与底板间由伸缩缝隔开,二者互为约束,但不能互相提供弯矩,将二者间的连结简化为铰结是合理的.指出渠道所受冻胀力和冻结力并不是独立的起作用,二者之间相互影响、相互依赖.针对小尺寸、整体性较好的梯形渠道提出...

| Abstract: | Through discussing about the damage characteristic and mechanism of frost heaving on the concrete lining of the channel with trapezoidal cross section,this article presents reasonable assumption and simplification,and its mechanical analysis and load calculation are done.This paper pointed out frost heave force and adfreezing force is not independent There are the relationship of interaction and interdependence between the two.For the small size of the trapezoidal channel,this article presents a method to d... |
