解釋
無襯砌隧洞-
The construction of the multiple - arch tunnel is deeply related to the form of center partition, the tunnel ' s section and excavation method etc. the change regularities of stress field caused by excavation are studied by 4 multiple - arch unlined tunnel model tests. the difference in lining for various multiple - arch sections is analyzed and the mechanics characteristics of center partition is discussed. then, a reasonable construction method for multiple - arch tunnel and a better section are put forward
