Strength Calculation and Analysis of Pier Cross Beam Support of Lijiatuo Double Track Bridge
The Lijiatuo Yangtze River Double track Bridge is adjacent to the existing Lijiatuo Bridge and adopts the construction method of double tower cable-stayed bridge.The P4 pier columns and beams are both ordinary reinforced concrete structures;The P4 pier beam is 2.5 m high and is an important structure in the bridge pier.For the construction of the crossbeam,the first step is to set up the bracket,and then pour concrete to form the crossbeam structure.At the same time,Midas/Civil software is used for simulation calculations to verify the rationali-ty of the construction process and design,and to effectively improve the construction efficiency.
