渠道混凝土衬砌冻害的受力分析及板厚计算

An Analysis on the Accepted Force on the Freezed Injury of Canal Conrete Lining and its Resisting Thickness Reckoning

本文对受冻胀的现浇混凝土坡板进行受力分析和荷载计算;并结合土力学温克尔理论中的基床系数法进行反力和内力计算;得出抗冻破坏的坡板厚度范围,结果较符合实际.

In the paper, We have analysed the accepted foree and reckoned the loading capacity of the concrete slab. We have used basic-bed coefficient method of Wingker' s theory to reckon the reactionary force and internal force and got the thickness scope for resisting freezed injury of slope concrete slab. The result accords with the actual situation.
