摘要
吊索长度计算在钢箱提篮拱桥的计算中较复杂,直接影响成桥线性,在实践过程中,选用简便的计算过程和方法有重要的意义。以某桥为例,介绍钢箱提篮拱桥吊索长度的计算方法和过程,并提出在计算过程中值得注意的几点问题,对类似工程计算提供借鉴和参考。
The calculation of hangers is very comlicated for the calculation of arch bridge. It has direct efforts on the bridge shape. Simple and practicle calculation process and method are significative. Based on an example of the calculation of some bridge, the article introduces the calculation process of steel box handle- basket arch bridge＇s hangers length. Then the authors bring up some problems should be paid attention during the calculation process. Hope it＇s useful to the similar engineering calculation, and it can provide some references and experiences.
