( China Railway First Survey& Design Institute Group Co., Ltd., Xi'an 710043, China)Abstract: To design and calculate the railway tunnel by load-structure mode, the main influence parameters include elastic resistance coefficient, water pressure, lateral pressure coefficient, arch camber angle etc. Using the ANSYS10.0 finite element software, in the range of parameters that is allowed by the code of railway tunnel, through comparisons and mathematical analysis when these change, these parameters' influences on structure calculation are explored, which can provide reference for the calculation of similar works in the further.
Keywords: load-structure method; elastic reaction coefficient; water pressure; lateral pressure coefficient; arch camber angle
