二重矢板壁構造物の振動時特性

Seismic Characteristics of Double Sheet Pile Wall Structures

水谷 太作(Taisaku Mizutani) 金子 忠男(Tadao Kaneko) 原 道彦(Michihiko Hara) 要旨 : 二重矢板壁構造物の設計法の検討に資するために,地震時の挙動特性について検討を行っ た。模型を用いた振動試験を実施した結果から次の知見が得られた。(1)固有振動数は,入 力加速度が大きくなるに従って減少する。これは,主として,砂の持つ非線形性,弾塑性 によるものである。(2)壁体幅 B の効果は,2 つの相反する形で現れる。すなわち,慣性力 として壁体を変形させる効果と,中詰セン断抵抗の効果である。(3)今回の試験の範囲では, 残留変形量は振動中の変形の動的成分よりも大きい。 Synopsis :

Dynamic characteristics of a static model of double sheet pile wall structures, which are important to design, have been evaluated in vibration tests on model structures. Experimental results are shown below. (1) Natural frequency decreases as the value of input acceleration increases. This fact is mainly related te sand properties, such as non-linearity and elasto-plasticity. (2) The effect of wall breadth is revealed as two opposite roles;one is the deformation effect as inertia force, and the other is the shearing resistance. (3) Residual deflection has a tendency to be larger than the dynamic component of deformation during deflection.
