Abstract: | By way of numerical simulation analysis of pedestrian channel already existing in a certain subway tunnel's undercrossing,the paper discusses unfluence of by part excavation of tunnel with long span on tunnel's structure.Calculation indicates that the methods for by part excavation of headings at both wall are capable of effectively controlling the settlement of subterranean channel's bottom. |
