摘要：
Elastic resistant coefficient, deformation and compressive moduli of surrounding rock in large-section loess tunnel are very important for design of tunnel. Based on the project of large-section loess tunnels along the new passenger dedicated line(PDL) from Zhengzhou to Xi'an, the elastic resistant coefficients, deformation and compressive moduli of surrounding rock in loess tunnels have been studied horizontally and vertically by plate loading tests. The formulas for these parameters mentioned above which are related to buried depth of tunnel are also provided.
