中文摘要: |
本文应用边界元法计算了强震下流体的非线性晃动及其对槽身的水平力及翻转力矩,将所得数值结果与线性解析方法的计算结果作了比较,分析了两类结果的异同点。计算表明:强震时,流体对槽身可能会产生很大的横向水平力,建议在抗震设计时考虑这一作用因素。 |
英文摘要: |
The boundary element method is applied to simulate nonlinear sloshing of fluid, dynamic horizontal force and overturning moment acting on the aqueduct body during earthquake. The computational results of BEM (nonlinear) are compared with that of linearized theories. The numerical results reveal that a great horizontal force acting on the aqueduct body may occurred during strong earthquake. This action must be considered in seismic resistance design. |
