| Abstract | Wu Cun Shan Tunnel in Xiamen Airport Road Phase I Project is a shallow-buried, large-span and hidden-digging tunnel which passes through high-density building cluster under complicated geological conditions. 67 buildings are being influenced by tunnel construction along the tunnel. In order to ensure the safety of surface buildings in the tunnel construction, CRD excavation method are adopted in some sections which initiates a precedent of construction of double-arch tunnel with CRD method in China. The effect of tunnel construction on frame structure buildings is analyzed through site monitoring of surface building settlement, crack development in this paper. The results show that excavation of tunnel face CRD1∼5 has the most important influence on the building settlement. The longer the construction period is, the greater building settlement and crack width change, and vice versa. Grouting in the tunnel can decrease building settlement caused by tunnel excavation effectively. The main reason that causes building cracking and development of cracks existed is uneven settlement. And the ability of the building to resist down concave deformation is stronger than that to upper convex deformation. While width variation of cracks lags behind variation of uneven settlement. Cracks caused by tunnel construction mainly distribute around the door and window openings in the longitudinal filler wall and the connection part between frame beam-column and filler wall. |

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.
