DISCUSS ON RIVER WATER EROSION AND ITS MEASUREMENT OF HYDRAULIC STRUCTURE CONCRETE

摘要

As one of the critical reasons for concrete ageing, water erosion and its measurement are more and more concerned by engineering field. This paper begins with analyzing factors which affecting anti-erosion of concrete, including consistence of concrete; self anti-erosion of concrete; ways of surrounding water contacting with concrete and so on. By summarizing various test methods and standards, comparing test term to actual engineering, the relevancy and limitation are proposed. Some advices about test methods of chemical erosion and standards of river water erosion for hydraulic structure concrete are suggested.
