| Abstract | Tunnel stability analysis is a geotechnical engineering problem characterized by many sources of uncertainty. In such case that rock and soil characteristics could not be defined by deterministic values, probabilistic technique would be as a suitable alternative. Naien water transporting tunnel is a circular tunnel with 6 m in diameter which is being excavated in such conditions and it is irrational to analyze the tunnel stability deterministically. To use probabilistic analysis, the best fitted distributions to rock mass characteristics were first obtained. Using Monte Carlo simulation method and considering four support systems, the distribution of factor of safety was obtained for each support system. To select the best support system, technique for order performance by similarity to ideal solution (TOPSIS) multi-attribute decision-making method is used by considering five criteria for each support system (as alternatives) including: probability of failure (using probabilistic method), factor of safety (using deterministic method), maximum displacement, cost and factor of applicability. The results of this research emphasize that the deterministic or probabilistic alternatives could not be separately such comprehensive technique for stability analysis and should be interpreted together. At last, using such TOPSIS application associated with stability analysis techniques can assist the engineers to effectively evaluate the support system alternatives for a tunneling project. |

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.
