- W2375388574 abstract "In this paper,stress analyses of the cracked and reinforced pile caps of the existing railway bridge are carried out respectively,so as to investigate on the mechanical reason of pile-cap's cracking and the efficiency of the method of reinforcement with prestressing force.In the meanwhile,this paper applies Ansys software to establish the pile-cap's space finite element model for numerical simulation analysis of stress characteristics.Further,the calculation results are compared with the actual crack situation.That draws the conclusion: there is tensile stress on the crack's developing area at the pile-cap's top surface,and the tensile stress is the mechanical reason that causes the pile-cap's cracking.In addition,the stress characteristics of the reinforced pile cap are analyzed after being reinforced with prestressing force,and then the relevant conclusion is: there is no tensile stress along the crack's development direction.All these shows that the method of reinforcement with prestressing force used in pile cap can improve the stress condition of the pile cap and can control the further development of the crack too." @default.
