Performance of buried flexible plastic pipe laboratory model studies and parametric analysis

Abstract

Buried conduits are the simplest underground structures which refer to the pipes culverts acqueducts underpasses etc of relatively smaller dimensions used for the transportation of fluid gases etc these are subjected to static and dynamic loads due to moving loads and also environmental evils such as blasts earthquake etc and thereby the mutual interaction between the newlinepipeline and the soil has to be taken into consideration Moreover less care and no control among the field engineers in laying and installing the pipelines poses a problem to the existing underground installations Such a situation necessitates the need for the study on the behaviour of buried pipelines with a view to understand the complex phenomenon associated with the selection of materials size and shape of underground installations nature of soil reinforcement of soil relative stiffness of soil depth of embedment method of installation nature of forces etc newline
