摘要
大跨度拱形结构基础常需设置倾斜基础底面,基础不仅产生竖向沉降而且还会发生水平 方向位移。基础的位移对上部结构的内力产生很大影响,因此,正确评估基础位移量以及准确分 析它与上部结构内力的相互影响是设计工作中一个非常重要的问题。作者针对上述问题进行了 分析,并提出了解决办法和应注意的问题。
There is not only horizontal displacement but also vertical settlement in the foundation of long span arch structure. Displacement of foundation has great effect on the internal force of the superstructure. It is virtually important to affirm the displacement of foundation and precisely analyse its effect on the internal force of superstructure. Aiming at these problems, the methods of resolution are put forward.
