Examples of port infrastructure, which have been designed until now, can be regarded as stock of experiences and technical knowledge in the past. Therefore, to researchers or designers who attempt to make full use of the informative stock, it is important that the information should be arranged and analysed.
　In this paper, the element dimensions and the design conditions of 180 examples of caisson type quaywall which had been designed untill 1988, are arranged, analysed, illustrated and tabulated from following points of view.
　1)Distribution of Design Condition.
　2)Distribution of Element Dimension and Relationship among Element Dimensions
　3)Relationship between Element Dimensions and Design Conditions.
　We believe that this paper can be used for empirical decision and setting of element demension or check on computerized design processes.
