摘　　要：为研究墩顶偏位及其他因素对格构式高墩稳定性的影响,文章利用有限元软件建立计算模型,首先研究格构式高墩墩顶偏位对其非线性稳定性的影响,研究结果表明,墩顶偏位对格构式高墩非线性稳定性的影响较为显著,在施工过程中,应密切关注桥墩墩顶偏位并及时进行纠偏处理。随后研究高墩截面尺寸和系梁对高墩线性稳定性的影响,结果表明,高墩截面尺寸和系梁数量存在一个最佳取值,在进行高墩设计时应计算选取该值。In order to study the influence of pier top deviation and other factors on the stability of lattice high pier,the finite element software is used to establish the calculation model.Firstly,the influence of pier top deviation on the nonlinear stability of lattice high pier is studied.The results show that the influence of pier top deviation on the nonlinear stability of lattice high pier is significant.In the construction process,the pier top deviation should be paid close attention to and corrected in time.Then,the influence of high pier section size and binder on the linear stability of high pier is studied.The results show that there is an optimal value of high pier section size and binder number,which should be calculated and selected in high pier design.
