Case study of different strain level of buried continuous water pipeline system for Delhi City

Pipelines are used for the transportation of liquid fuel, gas, oil, etc. sometimes cross unstable slopes, where earthquake-induced slope movements can easily take place but after the Gujrat earthquake it was realised how destructive could be the pipelines. So, an attempt was made regarding pipeline analysis and its larger study as accordance to the seismic movements. These movements can induce strains and stress in the pipe which can compromise the safety of the structure. The aim of the pipe stress prediction is to assess the failure risk and eventually to plan monitoring.

The topic “case study of different strain level of buried continuous pipeline system for Delhi city “ is initially dealt with, the soil interaction as discussed in which the finite element models are explained as well as the soil structure interaction is explained in detail and various site visit had been done to collect the borehole data required for the same and after that the complete study of different strain levels i.e. Axial strain due to operation, Axial strain due to earthquake excitation and Strain induced in the pipe line by friction at the soil pipe interface is calculated for the design criteria and the same is checked for various locations in delhi leading to the final use of pipes as mentioned later in detail.
