1) In this paper, an outline of the model test and the material test of Tori Arch Dam, and the mode of preparation of the model are given.<BR>We studied, by the model test, stress and deflection distribution on the upstream and downstream surfaces of the dam body at normal water load, stress in the thrust blocks and in the area along conduits, which cannot be sufficiently obtained from mere calculations, and finally investigated the safety of dam, the condition of destruction and particularly the safety of narrow area at the right bank foundation.<BR>The similarity relations between model and prototype are shown by the equations (1-1), (1-2) and (1-3). The scale of the model is 1/100 to the prototype as shown in Fig. 9 and 10. In the test within the elastic limit water pressure only was considered and it was given with mercury. In the destruction test oil jacks were used to represent water pressure, deposit pressure and dead load.<BR>2) We tested the mechanical properties and the composition of materials for the model, confi rming the next results. The elastic modulus of plaster-celite mixture definitely changed with varying composition and was constant regardless of the age of the material after completely dried. The Poisson's ratio of plaster-celite was 0.22 and was nearly equal to that of concrete.<BR>3) The elastic modulus was 4×104kg/cm2 in dam body and 104, 1.4×104, and 2×104kg/cm2 from the upper to lower part of foundation in model test. We preliminarily constructed the foundation, then excavated it and made the dam body slightly larger than the planning size. The body was then trimmed to the designed section by a special trimmer.
