ASSESSMENT OF SOIL CONSTITUTIVE MODELS FOR NUMERICAL ANALYSIS OF BURIED CONCRETE PIPE SYSTEMS

Notwithstanding the limitations of analytical procedures, the greatest error in currently available techniques for the analysis and design of soil-pipe systems, as well as most other problems involving soil-structure interaction, probably lies in the specification of material properties, especially those for the soil surrounding the pipe. Based on the premise that a continuum approach, as implemented by the recent development of the finite-element method and high-speed digital computers, offers the best hope for achieving major advances in our knowledge of soil-pipe interaction phenomena, the stress-strain behavior of the soil surrounding the pipe is usually considered to be one of the most important factors that affects the response of the system. Although a large variety of models have been proposed in recent years to characterize the stress-strain behavior of soils, all have certain inherent advantages and disadvantages which depend to a large degree on their particular application. This study is directed toward assessing qualitatively and quantitatively the relative merits and limitations of several of these models within the context of their use in the numerical analysis of soil-pipe systems involving reinforced concrete pipe.
