| Abstract: | The frost heaving damage can be thoroughly solved by laying a heat preservation layer in good condition under the rigid lining to prevent the frost heaving of the base soil. This is called the rigid lining canal with the heat preservation. The demands in structure design of the cross section of the rigid lining canal with the heat preservation have been developed according to the heat principle. The formula for calculating the heat preservation layer thickness and a calculation example have been given. Finally, two problems which are need to be further studied and discussed are also presented in this paper. |
