Abstract:

Conventional ways of assessing the effects of soil arching over buried conduits were examined by means of finite element analyses. It was found that neither of the conventional soil arching factors adquately reflect the response of buried conduits to overburden loads, and it is recommended that their use as a design tool be limited to the narrow empirical data base from which they were derived.
