| Abstract: | Research purposes:According to the construction organization arrangement of Ha-Da passenger dedicated line,two short tunnels need be broadened because of passing the carrying beams trains.So we have carried on a thorough research for ascertaining the cross-section inside outline of the special line for passenger train and the construction arts and crafts for resolving the key technique problem of the design and construction of the broadened tunnel. Research results:Aiming at the engineering demand that the carrying beams trains passing has been calculated fristly in the tunnel engineering of passenger dedicated line,we have investigated a pertinent idea about the design and construction of the boradened tunnel. |
