... the contribution of the buried pipe in stress bearing, provide more flexible interactions between falling mass, trench soil and the buried pipe, successfully detour the vertical stress to the sides of the pipeline, change the deflection mode to a sort of ring deflection, and protect the buried pipe against...

... of pipelines are technical, economic and social. In the case of a sewer network failure, illness and epidemics might result. In this paper, to protect the buried pipe, use of a three-dimensional geosynthetic (geocell) is investigated to reinforce the trench. Two series of three-dimensional full-scale tests...
