摘要:
近年来，随着山区公路建设的发展，桥梁的墩高也在不断增加，高墩桥梁的稳定性计算是桥梁设计的重要环节，故桥墩墩身的稳定性计算的重要性日益突显。本文在现有的稳定计算的基础上，进一步研究了桥墩上下两端均为弹性支撑的桥墩的稳定性计算问题，推导出相应计算公式。数值算例结果验证了公式的正确性。
Recently, with the development of mountain highway, the height of bridge pier has also increased. Stability of the high pier of bridge is a crucial part of bridge design; therefore, stability analysis of high pier is increasingly outstanding. In this paper, based on existing stability calculation methods, we make a further research into the problem of stability analysis of the high pier with elastic sup-ports in both sides and derive corresponding formulas, which are applied into actual bridge design. A further research into the problem of stability calculation of piers with elastic supports in both sides is made, and corresponding formulas are derived and applied into actual bridge design. Number examples also show the validity of calculation formulas in this paper.
