摘　　要：胶州湾全域的变态物理模型以团岛至薛家岛的狭窄口门处为单边界。依据相似理论,确定胶州湾全域物理模型的水平比尺和垂直比尺分别为1:700和1:70。由几何比尺给出模型的流速比尺、糙度比尺、水流时间比尺、流量比尺及潮量比尺。设计胶州湾整体模型的试验水池为宽40m、长50m、深1m。试验采用翻板尾门加双向泵以水位控制为主的生潮方式。确定尾门高度、底坎顶高程、尾门开度范围及其驱动电机功率,给出试验生潮泵的额定流量及蓄水设施的尺寸。为模型试验提供了理论基础,为施工设计提供依据。A distorted physical model is set up for the whole Jiaozhou Bay with its only open boundary at the narrow entrance spanning from Tuandao to Xuejiadao. According to the similarity theory, the model horizontal scale is determined as 1 ： 700 and the vertical scale 1 ： 70. Then the model scales respectively for current speed, bottom rounghness, flowing time, flow valume, and tidal prism are worked out of the geometric scales. The experimental pool for the model is 40 meters wide, 50 meters long, and 1 meter deep. A tail gate with turning plates, and reversible pumps are used in the experiment for tidal generation. Finally the tail gate height, the threshold height above the bottom, the gate opening width and the mortordriven pump power are specified for the maximum flow volume from pumps, and the measures of the water storage facilities. Therefore the theoritical basis for the model experiment and the foundation for the detailed model design and construction are laid.
