| Abstract | Series of compression waves and expansion waves caused by EMUs entering tennels at high speed will give rise to a series of tunnel aerodynamic effects: excessive pressure change will not only has effect on the fatigue life of EMU bodies and subsidiary structures in tunnels but also endangers the riding comfort of passengers. In addition, tunnel micro-pressure waves can even cause noise which effect the surrouding environment. Installing ventilation shafts inside tunnels is helpful to alleviate tunnel aerodynamic effects and the area of ventilation shaft is an important parameter. Dynamic model test system in Central South University was used in this paper to test and analyze the compression waves and expansion waves caused by trains entering tunnels and micro-pressure waves formed at tunnel exit, and to compare the influence of shaft with different area on the pressure change inside tunnel, the pressure change on train surface and the micro-pressure wave amplitudes. Test results show that the pressure changes inside tunnel and on train surface can be reduced effectively when the shaft area is 10% of the tunnel area; The larger the shaft area is, the smaller the tunnel micro-pressure amplitude will be. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
