摘要
研究用不同的计算方法,输入不同的地震波和地震烈度,同时结合路堤有关参数的变化,找出高填土路堤边坡稳定系数的变化规律。计算分析时采用静力法、拟静力法、静力有限元法和动力有限元法;动力反应分析时分别输入美国EL Centro地震波和按规范反应谱拟合的人工合成地震波。结果表明:路堤有关填土参数的变化对稳定系数的影响程度各不相同。
The aim is to at find out the changing pattern of stability factor of the high fill embankment by applying different calculate method, and comparative analysis with different input of seismic wave and earthquake intensity.In the caeulation and analysis the static, pseudo-static and dynamic finite dement methods are adopted.In the dynamic response analysis, the earthquake wave of EL Centro of the Unite States and the spectrum synthesize artificial earthquake wave arc inputed to make a comparative analysis so as to assess their influence to stable coefficient of the high fill embankment stability.
