Research on the Construction of the Underground Street Passage with FLAC 3D

With the fast development of scientific technology and city economy construction, Mining method adopted for shallow underground works, have being applied in the construction of underground passages at present. With typical Wenzhou underground passages embedded in silt and built by shallow mining excavation as the project background,3-D stress and deformation characteristics of a passage in the city center was analyzed by means of Finite Difference software FLAC3D, compared with field monitoring data of the underground street passage near the Second Affiliated Hospital of Wenzhou Medical College. Much important engineering information was obtained, such as the displacement deformation and stress nephogram of the passage, which can be referred for the construction of the similar underground projects in soft soil areas in future to make the projects more reasonable, safe and economical.

Fever of unknown origin in the elderly: nine years experience in China

This is a retrospective study of older patients admitted to the First and Second Affiliated Hospitals of Wenzhou Medical College, China, with a diagnosis of fever of unknown origin. The study took place from January 1998 to December 2006 among 102 patients who fulfilled the criteria. Infections were responsible for 50 cases (49.1%), followed by no diagnosis in 27 (26.5%), miscellaneous in nine (8.8%), neoplasms in eight (7.8%) and connective tissue disease in another eight (7.8%). Mycobacterium TB was the most frequent type of infection diagnosed.
