Abstract
For the mechanical properties of pipe joints, existing studies have mainly focused on flexible joints of ductile iron pipes and concrete pipes, and there is a lack of research on the mechanical properties of adhesive bonded joint of PVC pipes. By combining axial pullout prototype tests and numerical simulations using ABAQUS, this study investigated the effects of pipe diameter, socket gap, and loading rate on the axial mechanical properties of PVC pipe adhesive joints. Moreover, by building a buried PVC pipeline with 4 pipe sections, this study investigated the dynamic response of the adhesive bonded joint under different load amplitudes and different travel directions. The results showed that the seismic performance of the adhesive bonded joint is weak, and its axial pullout force is inversely proportional to the socket gap and proportional to the pipe diameter, while the loading rate has limited effect on it; under buried conditions, the longitudinal stress distribution at the top of the pipe is highly discontinuous, and the maximum stress in the socket is proportional to the traffic load amplitude, and the longitudinal travel direction is more likely to cause the failure damage of the buried PVC pipeline with adhesive bonded joint.
