BI Ji-hong, JIANG Zhi-feng, CHANG Bin. Numerical simulation for constructions of metro tunnels with short distance between them[J]. 2005, 26(2期 刊出日).DOI:
The situation of two tunnels with short distance between them will be encountered in the construction of metro
because of the limitation of topographical conditions
sometimes their spacing is beyond rule of code. In this paper
the ABAQUS program is used to analyze the actual status of the continuous construction of one number line in the second period of time of Shenzhen City Railway Traffic System by numerical simulation and shows the right line construction’s effect on the left line
including the ground surface subsidence
building
stress distributions and liner deformation. Meanwhile
some beneficial conclusions are drawn to offer constructions of tunnels with short distance between them.
