【摘要】 基于传递矩阵法,推导了考虑重力影响的单肢高墩稳定性总传递矩阵;对于双肢高墩,根据突变点的静力平衡方程,推导了点矩阵的表达式,并利用坐标转换矩阵建立起双肢高墩静力稳定性总传递矩阵。对高墩进行了稳定性分析,得到高墩的临界荷载。传递矩阵法力学概念清晰,电算程序简单便捷,可用于高墩稳定性分析。算例表明,该方法准确、有效。更多还原

【Abstract】 Based on transfer matrix method,total transfer matrix for stability of single high pier considering influence of gravity was got.For double high pier,according to the static equilibrium equations point mutations,deduced the point transfer matrix was deduced and using coordinate transformaton matrix,then the total transfer matrix of the double super high pier was set up,whose static stability analysis was done.Mechanical concept of transfer matrix method is clear,simple and convenient,which could be used for stability analysis of high pier.Examples show that the method is accurate and effective.更多还原
