Analysis on Gravity Dam Frost Resistance Durability Based on Freeze-thaw Damage: Guanyinge Reservoir in Liaoning Province as An Example
LI Ping;Benxi Manchurian Autonomous County Guanmenshan Reservoir Management Office;
Concrete design and construction are very important for concrete gravity dam,especially in the northern severe cold area. If the design is reasonable,measures are appropriate,serious breakage of concrete freeze-thaw on the dam can be effectively prevented. On the basis,Guanyinge Reservoir in Liaoning Province is adopted as an example in the paper for studying the basic principle and influence factors of freeze-thaw damage,prevention and control measures of gravity dam frost resistance durability are put forward,and the paper is of great significance to safe operation of concrete gravity dams.
