Abstract

Abstract

Integrated the calculation method of the surrounding rock static earth pressure in the Code for Design of Tunnel for Road and Railway,it was assumed that the fracture plane caused by earthquake in the soil of surrounding rock was balanced by the static equilibrium,in which the calculation formulas of tunnel seismic earth pressure were deduced and the seismic lateral soil pressure coefficient commonly used was converged into forms to be checked.The method belongs to general method of sliding wedge-earthquake intensity and compared with several common quasi-statics methods proposed for retaining wall structure,the D-value between the seismic lateral soil pressure coefficient and the static lateral soil pressure coefficient was close to the average value counted by other methods and at the same time the form was close to static earth pressure calculation formula,when horizontal earthquake coefficient was 0,the formula totally coincided with that of the static earth pressure,which was suitable for application by engineers.
