Analysis of the force effect of prefabricated cable tunnel corridor joints under vehicle load
Prefabricated cable tunnel(PCT)is prefabricated for factory and assembled onsite,whose upper vehicle load has a greater impact on the force performance of joints.In order to investigate the effect of the vehicle load on the performance of PCT corridor joints,this stud-y takes a PCT with cross-sectional size of 1190 mm×750 mm as an example,uses the meth-od of finite element analysis and investigates the force performance of joints under the influ-ence of vehicle load for different prestress values and soil stiffness.The research results show that when the vehicle load acts longitudinally on the PCT corridor joints,enhancing the bottom soil stiffness can effectively limit the longitudinal deformation of the structure;when the vehicle load acts transversely on the PCT corridor joints,enhancing the prestressing and lateral soil stiffness can effectively limit the transverse deformation of the structure.
