| Abstract: | Canal frost heave and its prevention is a major problem of canal projects for both construction and management in the seasonal frozen soil areas of north China.This article analyzed several existence problems in the development of technologies in this field: the rigid canal lining is heavily damaged by frost and bloated in canals;the construction technologies are lowly mechanized;the canal anti-seepage methods have some negative effects on the local ecological environment.To solve such problems,this article... |
