Abstract

Abstract: Aiming at the insufficient quantitative relationship between the obliquity and frost heave performance of canal lining， the mechanical model and numerical simulation were combined to study suitable U-shaped canal cross-section structure for local frost heave environment under different conditions， taking the D80 U-shaped canal as an example in Hetao irrigation district， Inner Mongolia. The results show that the smaller the obliquity and the narrower and deeper the canal， the greater the horizontal frost heave at the top of canal and the lager the stress at the bottom of canal. Conversely， the larger the obliquity and the wider and shallower the canal， the greater the vertical frost heave at the bottom of canal. The frost heave property of foundation soil and strength and thickness of concrete lining have a great effect on the frost heave resistance of canal. For loam soil， it is appropriate to choose 0.07m thick lining， 10° obliquity， and for silt soil， choose 0.08m thick lining， 13° obliquity.

Key words: U-shaped canal, mechanical model, numerical simulation, frost heave
