Time-Dependent Performance of Buried Pipes in a Consolidating Soil Medium

When pipes are buried in a partially or fully water-saturated soil, pore water pressure develops around the pipe and in the soil medium due to external loading such as embankments built over them. Currently, there is no information on the time-dependent performance of pipes buried in consolidating soil. The objective for this project is to determine the effect of backfill material under different conditions on HDPE and PVC pipes. The findings will be compared to the current specifications to see if changes need to be made. The tasks for this project will include investigating the performance of single and double walled HDPE and PVC pipes with consolidating backfill using a numerical model developed by the Principal Investigator. The influence of different drainage conditions will be evaluated as well.
