【摘要】 应用现代控制论中的状态空间理论 ,将坝体位移作为状态变量 ,导出拱坝动力响应分析的状态方程 ,建立状态空间迭代法的计算格式。由于状态空间法可同时算出各种应力和位移量 ,因此 ,应力与位移的精度较高。文末给出了一个拱坝动力响应问题的算例 ,所得计算结果与其它方法作了比较。更多还原

【Abstract】 Based on space state method in model control theory,this paper regards the displacement in dam as state variation,state equation for arch dam dynamical response is resulted in,the iteration computing scheme is establishedEvery stress and displacement can be calculated using space state method,,so the precision of stress and displacement is highAn example of the dynamical response of arch dam is givenThis result is compared with other methods更多还原
