Evolving urbanization and deterioration of old sewer and water supply infrastructure have greatly increased public expenditures on repair and replacement (>$1B/yr in Ontario). Most research on buried pipes has worked to address bending and buckling around the pipe circumference, considering the pipe in its initial burial configuration over the full service life. However, other factors also influence failure mechanisms and service lives, and these require investigation:

不断发展的城市化和旧下水道和供水基础设施的恶化大大增加了维修和更换的公共支出（安大略省每年10亿美元）。大多数关于埋地管道的研究都致力于解决管道周围的弯曲和屈曲问题，考虑到管道在整个使用寿命期间处于初始埋地结构。然而，其他因素也会影响失效机制和使用寿命，这些都需要调查：
