| Outline of Final Research Achievements |
This study measured detailed temperature distribution around buried pipes under the pavement and vertical stresses in the ground, as well as seasonal changes of incremental stress exerted by vehicle wheel loads for damage risk assessment of buried pipes beneath pavements in cold regions.
Results revealed that these measured values change significantly as a result of the ground’s freeze-thaw process. In addition, we found that the incremental stress in the ground increases with the vehicle weight and that the rate of increase changes with freezing and thawing. The stress distribution (transmission) in the ground was also found to change with freezing and thawing.
