某悬浇桥施工临时墩受力分析OA

Long span continuous beam bridges are generally constructed with cantilever pouring.In order to reduce the stress on the main pier during construction and to enhance structural stability,temporary piers are often installed at the main pier and block 0.The stress situation of temporary piers is complex,and according to traditional calculation methods,it is difficult to accurately analyze the stress of temporary piers during construction.To accurately calculate the stress on temporary piers during construction,this paper uses a large finite element program to simulate various working conditions during the construction process,and to calculate the displacement and stress of temporary piers under each working condition.After analysis,it has been shown that with the changes in construction conditions,the stress on temporary piers varies significantly.It is necessary to simulate the entire construction process to calculate the maximum displacement and stress on temporary piers and to ensure their safety.
