Parameter calculation of and reinforcement design for concrete anchor block in long span spatial cable plane cable-stayed bridges
This article takes the Hengqin Yujiang bridge in Guangxi as an example,and uses spatial analytical geometry method to derive the formula for calculating the parameters of concrete anchor blocks suitable for spatial cable plane cable-stayed bridges.Combined with data processing software,batch solving can be achieved and design efficiency can be improved.The three-dimensional solid finite element method was used to calculate and analyze the spatial stress behavior of concrete anchor blocks,and the reinforcement design of the anchor blocks was carried out in combination with standard formulas to avoid the occurrence of cracks during the operation stage.
