Abstract
The purpose of this study, loading location of surcharged load for buried pipe, performed numerical analysis in order to investigate the structural behavior of buried pipes due to the change of the buried depth.
The results of numerical analysis, the maximum displacement to occur as loading location of the surcharged load away from the center of the buried pipe is reduced. The maximum displacement is reduced to occur as buried depth becomes deeper. The loading location of the surcharged load is positioned within the diameter of the pipe, the maximum stress generated is increased, and the loading location is positioned beyond the diameter range of the pipe, the maximum stress generated is reduced. Buried depth is hardly affected by the loading location of the surcharged load when the buried depth deeper than the width of the surcharged load.
