基于midas的平曲线半径为40m连续箱梁计算分析

摘要

采用midas程序对平曲线半径仅为40m的连续箱梁进行精细化分析，比较当采用不同支承形式后桥梁的各种效应结果，得出极小半径箱梁的支承选取的规律及注意事项，同时给出计算时需注意的地方。%〔Abstract〕 After the analysis of a Box-Girder in R=40m with Midas, it is compared the effect when the Box-Girder is given a different supporting condition, and it is found that the rule of select supporting condition when the Box-Girder locates in a small curve, and bring forward the advertent point in calculation.
