| 内容記述 | In designing the construction of the artificial fish scheme, the external forces taken into consideration are the maximum one's act on the fish scheme when it's loading, transporting, and putting at the sea bottom. When the artificial fish scheme lands at the sea bottom, the impact force is generally produced. Then it is the most dangerous condition for the artificial fish scheme. The intensity of this impact depends on the weight and the falling velocity of the fish scheme, the physical property of the sea bottom and the form of the fish scheme. The purposes of this experiment are following. 1 Estimation of the reaction coefficient (K) of the rock base and concrete base. 2 Establishment of the method for designing the construction of artificial fish scheme. (The method is that the inertial force is converted into the gravity force.) Under in-air test of artificial fish scheme (Fig. 1, 2) and the model (Fig. 3), we measured its strain, falling, velocity, acceleration and crack. In this experiment, we made clear as follow. 1 Coefficient of reaction Rock base; ~10⁴ kg/cm² Concrete base; ~10⁴~10⁵ kg/cm² 2 The weight of the fish scheme, calculated back on the strain of the beam at its landing is approximate to the weight calculated by the equation (1), (2). R = Kεᵐ …. (1) σ̅ԍ=Kεₘₐᵪᵐ/V .... (2) here, R: reaction of base, K: coefficient of reaction ε: subside quantity of base, m: multiplier V: volume of artificial fish reef, σ̅ԍ: converted weight εₘₐᵪ: maximum subside quantity of base | |||||||||||||||||
