The formation mechanism of surrounding rock pressure in large-section tunnels of underground excavation is still unclear. The traditional methods for calculating surrounding rock pressure have certain limitations. Based on the theory of pressure arch and parameter sensitivity analysis, the internal and external boundaries of the pressure arch are solved by numerical simulation. The loose pressure is obtained according to the distance from the inner boundary to the inner wall of the tunnel. The pressure arch deformation is analyzed based on the Winkler model. The surrounding rock pressure is calculated, and the surrounding rock pressure based on the pressure arch theory is calculated. The calculation method of surrounding rock pressure based on the pressure arch theory large section tunnel is proposed. The orthogonal experimental design method was used to select four representative factors: tunnel depth H, span B, internal friction angle φ and rock weight γ. The calculation results of each group of experiments were compiled and multivariate linear regression was used. The method is statistically analyzed, and finally, the calculation formula of the surrounding rock pressure of the large-section tunnel affected by multiple factors is obtained and applied to the calculation of the surrounding rock pressure of the metro station.

“…A number of parametric studies have been carried out using DEM to estimate the behavior of rock masses with or without cavern, with one set or more than one set of discontinuities (Kulatilake et al, 1992;Cundall, 1993;Souley and Homand, 1996; Shne and Barton, 1997; Bhasin and . The DEM has also been applied to the construction sites containing underground structures and the numerical results have been compared with the measured performance (Bhasin et al, 1996;Souley et al, 1997). However, the cases using DEM to assess the performance of underground caverns are still few, and the standard routine of DEM modelling, such as the determination of mechanical properties and the modelling procedure have not been established.…”

The stability and support eŠects of large-scale underground caverns located in jointed rock masses are principally ruled by the mechanical behavior of discontinuities. The major deformations of the host rock masses containing underground caverns originate from the normal and shear movements among the walls of discontinuities. Therefore, in the numerical simulations of the deformation behavior of underground structures, how to accurately model the discontinuities becomes a key problem. In this study, a 2-D distinct element code, UDEC, was used to analyze the deformation behavior of an underground cavern of a pumped storage power plant, based on in-situ geological data. The validity of numerical simulation was evaluated by comparing the numerical results with the site measurement data at two cross-sections of the cavern. Some local deformation behavior of the cavern aŠected by the characteristics of discontinuity distributions was discussed. The in‰uences of cross-sectional shape of the cavern and the orientation of initial ground stress on the performance of cavern were evaluated. The simulation results revealed that the orientation, position and density of discontinuities as well as the cross-sectional shape of a carven in‰uence its deformation behavior and stability signiˆcantly.
