摘 要: 将精细传递矩阵法应用于对高墩的稳定性分析中,针对动力稳定性分析,提出将精细传递矩阵法与振型分解反应谱法相结合,以推导高墩在动力作用下的动力反应传递矩阵,并根据动力失稳判别准则确定高墩的动力临界荷载。比较该方法与ANSYS的计算结果,验证了该方法的准确性和有效性。通过数值算例证明所提方法力学概念清晰、计算快捷,能很好地反映高墩的力学传递特征。该理论适宜于工程实际应用。
关 键 词: 道路工程;稳定性;精细传递矩阵法;高墩;动力反应传递

Abstract: In this paper, the precise transfer matrix method was used in the stability analysis of high pier. In the light of the dynamic stability analysis, we put forward that let precise transfer matrix method combine with vibration mode decomposition response spectrum method to deduce the transfer matrix of dynamic response for high pier under dynamic action. According to the dynamic instability criterion of high pier for dynamic stability analysis, the dynamic critical load of high pier was got. The comparing of the method with ANSYS calculation results proved the accuracy and effectiveness of the method. The results showed that mechanics concepts were clear, calculation was fast and mechanical transmission characteristics were reflected well. The theory is suitable for engineering application.
