| Abstract: | This paper presents a simple procedure for calculating rockfall penetration and ground impact stress for design of pipeline
burial depth. Rockfall may damage pipelines by penetrating through cover soils and damaging the pipeline by puncture or excessive
impact stress. Design engineers may face a challenging question regarding what burial depth is required for adequate pipe
protection. Greater burial depth may provide better protection; however, there are usually site and economic constraints.
This paper discusses a simple procedure for calculating the maximum rock penetration and ground impact stress due to rockfall.
The procedure may be used to estimate the minimum burial depth required to protect pipelines from rockfall damage. A case
study involving a large boulder that fell down a slope and landed on a buried high-pressure gas pipeline is presented to demonstrate
and verify the procedure. A calculation was performed before the removal of the boulder to evaluate whether any damage was
made to the pipeline. The calculated results agreed well with the actual conditions observed after the boulder was removed. |
