Abstract: Voluminous statistical data on the breakage and leakage of pipelines occurring frequently in water supply and drainage engineering, were collected and analyzed to find the causes and solutions for the breakage and leakage. Then the original parameter method of foundation beam on elastic semi-infinite plane subgrade was applied to verify the statistical results. Numerical computational results showed that the performance of the original parameter method of foundation beam was satisfactory.

Key words: numerical analysis, buried pipe, breakage and leakage
