| Abstract | During the long-term stability assessment of underground disposal repositories buried in sedimentary formations, one of crucial scientific problems is to determine parameters of site formations. The analysis of response of the pore pressure due to atmospheric loading provides a possible way of accurate estimation of formation parameters. In this paper, an analytical solution of response of the pore pressure to atmospheric loading was derived starting from the Biot’s poroelasticity, and its corresponding numerical solutions were developed by finite element methods for 1D and 2D situations. With comparison to the analytical solution, the experimental results show that the numerical schemes sound reasonable to implement the assessment of response of the pore pressure in horizontal multilayer sedimentary formations. In particular, it is effective for a 2D model over large area with consideration of background horizontal groundwater flow. A highlight of this work is to construct a reasonable approach to capture responses of the pore pressure to atmospheric loading, and at the same time to provide the feasibility of integrated analysis of well monitoring data of pore pressure variance in Horonobe Underground Research Laboratory (URL), Hokkaido, Japan. |

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.
