Fully Coupled Flow Deformation Analysis of Buried Concrete Pipe Using Finite Element Software PLAXIS 2D

This study investigates the behavior of buried concrete pipes and changes in subgrade support capacity due to heavy rainfall-induced flooding at the ground surface and reduction of shear strength of the supporting soil due to the infiltration and leakage from the pipe using the finite element software PLAXIS 2D. A stormwater pipe of diameter 2.8 m and thickness 0.2 m was selected according to the ASTM C 14. The maximum flood head and the infiltration rate were chosen based on the record after Hurricane Florence occurred in September 2018. The effect of the individual occurrence and simultaneous occurrence of flooding, infiltration, and leakage on the behavior of the buried pipe was analyzed. Results indicated that the simultaneous occurrence of the three events induced the highest deflection of 3.80 mm. The bending moment and shear force increased from 15.06 kN m/m to 23.2 kN m/m and 22.65 kN m/m to 36.2 kN m/m, respectively, due to the combined events.
