A STUDY ON EFFECT OF PILE GROUP USING SILICONE SOIL MODEL
|
抄録（英）：
In oder to investigate basic property of pile group effect on both dynamic stiffness and seismic force distribution, soil-structure model tests are carried out. As the model tests are based on similarity law, such as1/50 in length, l/1.2 in density, etc., the soil model is made of silicone rubber whose Young's modulus is about 35 kg/cm■. From the impulse hammer test and static loading test, it is shown that 'dynamic stiffness group factor', which is defined as the ratio of the dynamic stiffness to the sum of static stiffness of the individual single piles, of rectanglar pile group can be closely estimated by the product of that of series pile group and parallel pile group. And from shaking table tests, it is shown that the lateralforce distribution factor of comer piles to the inner pile are more than two times at 3×3 pile group.
