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。
Based on the transfer matrix method, the total transfer matrix of single-limb high pier considering the influence of gravity is deduced. For the high-pier with two limbs, the expression of the point matrix is deduced according to the static equilibrium equation of the transition point and the coordinate transformation matrix is established Starting from the high transfer pier static stability of the total transfer matrix. The stability of high pier is analyzed and the critical load of high pier is obtained. Transfer matrix method mechanics clear concept, computer program is simple and convenient, can be used for high pier stability analysis. The example shows that the method is accurate and effective.
