摘要
在对长江巴东公路大桥桥址区工程地质条件研究的基础上 ,采用有限元法计算了桥墩地基应力分布和桥墩基桩的桩端沉降量 ,认为主桥墩处的应力改变最大 ,同时主桥墩的沉降量也最大 ,影响深度达桩端下 5 0~ 60 m,辅桥墩处的应力改变和沉降量较小 ,相对来讲 。
The engineering geological conditions of Badong Changjiang Highway Bridge are very complex.Based on the study of the engineering geological conditions,the baseground stress distribution of the bridge pier and peg end settlement is calculated by FEM.The result indicates that:the stress change around the main bridge pier is the greatest,and so is the peg end settelment of main piers, while the infection depth is 50-60 m under the peg end,and that the stress change and the peg end settelment around the assistant bridge pier are less.Meanwile,the stress change in the northern side is greater than that in the southern side.
