@@@@At present,the Beijing-Shijiazhuang section of middle route of South-to-North Water Transfer Project lining plate suf-fered different degrees of frost heaving, cracks and other damage phenomenon.The reason can be roughly classified into construction technology, geological environment,daily maintenance etc. But precisely because of these smal cracks,coupled with the accumulation of time,the rain pouring,frost heaving continuous aging intensifies,sealing strip, it entered a vicious spiral. According to the author explored crack problem of canal lining board.
