对于先简支后连续法施工的连续梁板桥 ,设计了逐次接长连续梁板逐次拆除临时支座的多次体系转换法 ,与全梁接长到总长后一次拆除临时支座的一次体系转换法比较 ,两种体系转换法分别使连续梁产生的超静定内力值很接近 ,说明多次体系转换法是安全的 ,而且多次体系转换法可使施工过程中边墩的侧向挠曲及弯矩明显减小 For the continuous beam-slab bridge with simple support and continuous construction, the system of successive transition from continuous slab to successive support was designed, and the system of one-time removal of temporary support Compared with the conversion method, the two system conversion methods respectively make the value of the statically indeterminate internal force produced by the continuous beams very close, which shows that the system conversion method is safe, and the system conversion method can make the lateral deflection of the side piers during construction Curves and moments significantly reduced
