摘要

在对湘黔线资水大桥的评估中

提出了桥墩在受各种不同冲刷程度的影响下

通过改变基底的支承方式模拟基础底部被掏空的途径

应用有限元方法进行基底压应力和墩顶位移计算分析的方法。该方法揭示了基底最大压应力等于基底容许压应力时的极限掏空面积和考虑墩顶最大横向、纵向、竖向位移的因素而引起基础的各种变形与应力发生剧烈的变化

导致基础失效的基底掏空面积

为受冲刷桥墩的稳定性分析提供了有力的依据。

Abstract

For evaluation of the Zishui Bridge of Xiang-Qian Railway Line

a method which uses the finite element method to calculate and analyse compressive stress of the foundation base and displacement of the pier top in influences of different scouring degrees

is presented. The method adopts an approach of changing support pattern of the foundation base to simulate the undercutting of foundation base. This method not only reveals the ultimate undercutting area when maximum compressive stress is equal to allowable compressive stress of the foundation base

but also offers the undercutting area of the foundation base for invalidation of the basement which results from the intense variation for different deformation and stress considering the factor of maximum transverse longitudinal and vertical displacement. A powerful reference is presented for the stability analysis of the scoured pier.
