CYLINDRICAL CAISSON BREAKWATER: STRAIN MODEL TESTS

[摘要] The distribution of shook pressures on a vertical face breakwater is so random from one shock to the next that the determination of the internal forces in a thin-balled reinforced-concrete structure is difficult even when a large number of pressure cells is used in a model test. Therefore a technique has been developed that allows the direct determination of the internal stresses by means of strain gauges. The new technique has been applied to a breakwater consisting of a series of cylindrical caissons. The results show that a strain gauge model is more advantageous than a pressure cell model because of its simpler data analysis and better determination of the quantities required for design.
