| The Freezing and Thawing Stability of Plastic Film Antiseepage Canal |
|
|
| Abstract: |
| This paper designed an In-door freezing/thawing unstable test on quite a
large scale with the simulati of work conditions of protecting layer,as well as analysed
and discussed the mechanical properties when thawing slide occulred between saturated
soil and plastic film and the probleas in selection of desigh antisliding paraneter. |
| Key words: antiseepage canal with plastic film,antisliding index,freeging/thawing unstability |
