摘要
中低速磁浮作为一种快速、高效、环保、高技术含量的运输方式,正受到社会越来越广泛的重视。研究表明中低速磁悬浮适宜采用单箱单室后张预应力混凝土简支梁。为验证小半径曲线下采用简支箱梁的合理性,保障线路安全运营,结合实际工程,建模、计算和分析了曲线半径对简支箱梁的影响,验证了R=200 m曲线半径下采用简支箱梁的可行性。
As a high speed,high efficiency,environmental protection and high technology content of transport mode,the mid-low speed maglev is paid more and more attention of the society.The study shows that the single-box single-cell post-tensioned pre-stressed concrete simple-supported girder is suitable to use for the mid-low speed maglev.In order to verify the rationality of simple-supported box girder to be used in small radius curve,to guarantee the safe operation of line and combined with the practical projects,the model is established to calculate and analyze the effect of curve radius on simple-supported box girders,which can verify the feasibility of using the simple-supported girders in curve radius /?=200 m.
