摘　　要：廊道结构是坝中不可或缺的结构,随着施工技术的不断发展,大坝高度的不断增加,其在大坝建设中的地位越来越突出。论文通过理论分析,选取并建立有代表性的计算模型,结合已有的试验数据,研究廊道结构的破坏机理和破坏过程,提出以裂缝的特定长度来定义廊道结构极限状态的建议,并归纳出主裂缝长度的计算公式。As an integral part of the dam, gallery structure is playing an increasing important role in dam construction with the development of construction technology and dam height. The failure mechanism and failure process of gallery structure is analyzed by establishing typical computation model, taking into account of the available experimental data. It is suggested to define the limit state of gallery by the given length of crack, and the formula for calculation of main crack length is concluded.
