【摘要】 采用剪切楔法和反应谱法,分别在不考虑土石坝材料的非线性和考虑土石坝材料的非线性的情况下,计算了土石坝的各阶自振频率。研究表明,考虑材料的非线性,将会降低高土石坝的自振周期;两种情况下计算的土石坝在地震作用下的沿坝高方向的加速度分布规律,除坝顶位置外基本相同。更多还原

【Abstract】 Combined with shear wedge method and response spectrum method,respectively,without considering nonlinear of earth rock dam materials and considering the nonlinear under the condition of earth and earth rock dam materials,to calculate natural frequency of earth rock dam. Studies show that: Considering the nonlinear material,will reduce the natural frequency of earth rock dam,two kinds of cases of calculation for earth rock dam under earthquake acceleration along the dam height distribution is mostly the same except the top position. For earth rock dam aseismic calculation,nonlinear material can not be easily ignored in earth rock dam.更多还原
