Prevention and Anti-frozen Technical Mehtods of the Channels in Alpine Region

The prevention and anti-frozen technical methods of the channels in high cold regions is presented. The methods are all based on the research of the hydraulic structures of Heilongjiang Provincial Hydraulic Research Institute which are from the research result in the recent twenty years. The research includes the determination method of the anti-frozen design parameters, the outlines of the prevention and anti-frozen technical methods of the channel lining projects, etc. It offers some references for the similar engineering.
