摘要
宜宾长江公路大桥主桥为双塔PC梁斜拉桥。通过对 其分析,明确各施工阶段典型受力状况,并根据该桥的结构特 点,应用结构分析程序对施工和运营阶段进行总体结构静力分 析,验证了施工方案的可行性和结构设计的安全性,并对施工 阶段的操作提出建议。
The main bridge of Yibin Changjiang River Highway Bridge is a cable-stayed bridge with two towers and prestressed concrete beam.Through the analysis, typical force cases in every construction stage are determined,and according to its structural characteristics,the structural analysis programs are used in simulating structural static analyses in the construction stage and the operation stage.The results of the analysis prove the feasibility of construction project and the safety of structural design.And some reasonable suggestions are also brought for the operation of construction stage.
