摘要

Fourteen miles (22.5 Km) of Reinforced Concrete Cylinder Pipe (RCCP) mainlines for the Pima-Maricopa Irrigation Project (P-MIP) were designed, manufactured, and constructed between 1998 and 2002. The pipe manufacturer designed the P-MIP RCCP pipelines in conformance with the procedures presented in Chapter 7 of American Water Works Association (AWWA) Manual M9 and additional procedures presented in this paper. The history and evolution of the semi-empirical and rational design procedures used by pipe manufacturers and agencies between 1919 and 1974 are presented and discussed. The performance record of pipelines designed in conformance with these procedures is excellent. The current AWWA M9 RCCP design procedure for resisting flexural and axial stresses from combinations of internal pressure and external load conditions, which evolved from the earlier procedures, has been adopted by the manufacturers and users of RCCP. Radial tension and shear (diagonal tension) analysis procedures with two design examples are presented. Using the M9 design procedure with the minimum wall thicknesses listed in the AWWA C300 RCCP standard is adequate for normal loading conditions. Calculating the shear (diagonal tension) in the pipe wall and resulting stresses and radial tension strength is useful in determining the required wall thickness and compressive strength of the pipe for special loading conditions, such as high earth cover loads. Recommendations for enhancements to the current M9 design procedures for RCCP are presented and discussed.
