為了設計穿過壩身的水管,設計廊道,設計縱向伸縮縫,繪製主应力軌跡線等,壩身內部應力的分析是必要的源?898年列维提出析楔內应力的方法后,各國陸續提出了許多分析重力壩內部应力分析的方法襁€沒有看見一篇文章對這些方法進行綜合性的討論,加以分类比较,介绍各法的优缺點或提供有关工程应 In order to design the water pipes through the dam body, design the corridor, design the longitudinal expansion joint, draw the main stress trajectory, the analysis of the internal stress of the dam body is necessary. After Levi proposed the method of analyzing the stress in the wedge in 898, Many countries have put forward many methods to analyze the internal stress of gravity dam. There is no article to see the comprehensive discussion of these methods, to classify and compare the advantages and disadvantages of each method or to provide relevant engineering
