The Concrete Expansion Phenomenon in a Concrete Gravity Dam

摘要：

　　Based on gradual permanent uplifting of one dam body registered by vertical displacement monitoring data, through comprehensive and comparative analysis of results of other monitoring items, this thesis concludes that the phenomenon of year by year dana concrete expansion does exist.According to these findings, issues which need to pay attention to and worth further researching, such as the impact of different aggregate composition and admixture on concrete durability, the requirement of structure stress status on strength and so on are raised.
