CORRELATION AND ANALYSIS OF CALCULATION VALUCS OF VERTICAL PRESSURE OF WALL VOCKS OF LARGE-SPAT TUNNEL

Calculating correctly the pressure of wall rocks is very important to the stability of tunnel structure in the process of tunnel's design and construction.An engineering case of large-spat tunnel is taken to compare different calculation values of several tunnel pressure of wall rocks expressions used widely now.It aims to study further the applicability and oneness of each pressure expression.
