斜拉桥桥塔桩基等效计算方法

The equivalent calculation of the pile foundation for the cable-stayed bridge tower

通过对斜拉桥桥塔桩基的等效计算,归纳总结了一种简单的桩基截面尺寸及桩长来替代实际比较复杂的桩基结构及桩所穿越的多种土层的方法,指出在桥塔设计时,应按照等效的桩基建立桥塔计算模型,使得桥塔有限元计算模型简单而且不失真,准确反映桥塔实际受力情况。

The pile of the cable-stayed bridge towers were equivalent calculation, in order to identify a simple cross-sectional dimensions of the pile and the pile length to replace the complex pile structure and the variety of soil which was through by the pile, in the design of this bridge tower, you can create the computational model of bridge tower in accordance the equivalent pile, making the bridge tower finite element model is simple and without distortion, accurately reflect the actual stress situation of the bridge tower.
