| Abstract | Trenched pipelines subjected to large lateral soil movements were studied to quantify mitigative effects of trench geometry, backfill soil material and strength on the force-displacement behaviour in cohesive soils. Experimental and numerical models show a good agreement in terms of undrained ultimate forces, which are also consistent with design guidelines and previous studies. Undrained lateral pipe resistance factors, are assessed in terms of soil strength and soil weight in uniform soil. A normalised pipe displacement rate characterizes a transition in the lateral resistance from undrained to drained conditions is presented. The presence of a trench backfilled with material weaker than the native soil softens the lateral load-deformation (p-y) response compared to that of the same pipe buried in native soil. An increase in the trench width increases the pipe displacement to peak load. The lateral interaction force is much lower in a pipe with a wider trench than a narrower trench prior to reaching the peak load. The peak load occurs after pipe touches the trench wall and is controlled by the native soil strength. It decreases slightly with increase in the trench width because of upward movement of pipe prior to reaching trench wall. The mitigative effects of trench wall inclination are also demonstrated. A simple approach to determine the p-y response for a trenched pipeline backfilled with material weaker than the native soil is proposed. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
