Theoretical and Experimental Analysis of Corrugated Gravity Pipes

A basic parametar to be determined in the structural design of buried pipes is the pipe ring stiffness, which is a function of modulus of elasticity of the pipe material, the moment of inertia of the pipe wall section and the mean pipe diameter. Methods for the structural design of buried pipes, such as the German ATV method in its original form, have been developed for smooth pipes. In this paper the existing calculation methods are upgraded for corrugated thermoplastics pipes type VARGON. The verification of the theoretical analysis is made by experimental analysis. Experimentally obtained results of the pipe ring stiffness are in good correlation with the theoretical analysis and with the pipe characteristics declared by the corrugated pipe manufacturer.
