摘要
结合泉州市朋山岭立交工程,采用MIDAS有限元分析软件,对匝道曲梁的支座反力进行了计算。分析了恒载、活载、预应力荷载作用下的支座反力分布情况,重点研究了支座脱空的主要影响因素,得出了一些有益结论。最后对曲线梁的支座偏心情况进行了归纳整理,便于以后的工程应用及研究参考。
Taking Pengshanling Interchange project in Quanzhou for example,the bearing counterforce of ramp curved beam is calculated by means of MIDAS finite element analysis software.The distribution condition of bearing counterforce is analyzed under dead load,live load and prestressed load.Moreover,the main influence factors of bearing void are researched especially and some meaningful results are given.Finally,the bearing eccentricity condition of curved beam is summarized to provide references for similar projects in the future.
