| Abstract | This paper presents a systematic approach with detailed step-by-step procedures for assessing safety risk of existing bridges in tunnel construction. The potential safety risk of a specific adjacent bridge is assessed within four different risk levels, with the spatial neighbor relation (hazard component) and the bridge health condition (vulnerability component) taken into account. Corresponding preventive measures for bridges at different risk levels are further provided according to risk assessment results. A reasonable balance between the project system safety and budget constraints is reached, where the assessed risk level plays a decisive role in the adoption of numerous simulation analysis tools. The proposed approach is applied in the construction of Wuhan Metro Line 2 (WML2) as a case study. The impact of the foundation excavation on adjacent bridge piers is further analyzed. Results demonstrate the feasibility of the developed approach, as well as its application potential. |

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.
