This paper focus on the evaluation of the effects that contribute most to the deformation of buried plastic pipes, trough simulation by design of experiments (DOE). The results are in agreement with those obtained by the application of statistical analysis such as the method of principal components and fator analysis, and are also consistent with the results of field tests, confirming thus the effectiveness and suitability of these methods for prior assessments, with great economy of resources.
