摘　　要：从支承形式上来看,简支转连续梁桥主要包括单支座和双支座两种主要的结构形式.为了更好地发挥简支转连续梁桥的特点,了解该类桥梁不同支承形式的受力性能,对两种支承形式进行了支座沉降、温度变化以及双支座脱空受力分析,并得出了相应结论供相关人员参考.From the support forms,the simply supported-continuous bridges have mostly two main structural forms： single prop and dual prop.To better exert the traits of the simply supported-continuous bridge and understand the mechanics of this bridge in different support forms,a mechanical analysis is made through the support sedimentation,temperature change and deviation of dual prop.Through the analysis,the relevant conclusions are educed and a consult to the correlative personnel for servicing the projects is given.
