In practice, asymmetric formation disturbance occurs due to the sequence of excavation though parallel double-track tunnel is a typical symmetrical engineering. Based on shield tunneling project section Suzhou Rail Transit under subgrade Shanghai–Nanjing Expressway, finite element model was established obtain numerical solution that validated by measured data guarantee reliability. According co...
Background and objectives: Urinary tract infection is one of the most nosocomial infections with different antibiotic resistance pattern. This study was aimed to investigate the pattern of susceptibility and resistance of uropathogenic E. coli strains that had been isolated from those who referred to the private laboratories in Khorram-Abad city. Materials and Methods: This empirical s...
This article summarizes the current construction methods of prefabricated utility tunnels. (1) The proposed cast-in-place tunnel project was used as a background for this study. (2) original structure divided into components, and connection composite slabs mortise tenon joints were to propose new type concrete method. After completing design tunnel, numerical simulation analysis actual stress s...
nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. in some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. theref...
