| 摘 要： | 曲线箱梁桥目前还缺乏比较实用的设计方法．本文对曲线箱梁桥的现有设计方法作了研究，并推荐一种实用设计方法：采用空间梁单元，每个节点取六个自由度；等效梁格的模拟考虑了横向梁格附近有无横隔梁的情况．结果证明，这是一种简便、较精确的设计方法．

| Abstract: | Presently,no methods available are regarded as practical for designing curved box girder bridges. In this paper, some existing design methods are reviewed and a practical design method is presented. Space beam-element with 6 degrees of freedom for each node is adopted in the method:diaphragm are taken into consideration in the simulation of equivalent beam grid. The results prove that the method is simpler and more accurate. |
