本文运用桥梁计算软件“桥梁博士”对既有设计桥梁方案选择进行进算与分析，从受力性能及工程造价等方面阐述悬臂浇筑施工法的优越性，对比分析满堂支架法在方案改选中存在的问题，对于桥梁设计具有借鉴意义。% This thesis focused on calculating and analyzing the given bridge design proposals by using Doctor Bridge,a bridge calculation software. It presented the advantage of the cast-in-place cantilever method on the basis of mechanical properties and engineering cost, and it compared and analyzed problems during re-choosing the project via the full space supporting method.It could be very beneficial for bridge designing.
