extra-long wheelbase
3.DESIGN AND CONSTRUCTION OF A 96 m EXTRA-LONG PRESTRESSING CABLE FRAMED BEAM PROJECT
5.Control Measurement and Hole-Through Survey within Parallel Adit of No. Ⅱ Line in Qinling Extra-Long Tunnel
6.Application of Erbium-doped Fibre Amplifier (EDFA) in Optical Communication System with 220kV Extra-long Transmission Line
7.The research result satisfied the main technical requirement for the construction of extra-long rubber dam projects, made the design for extra-long filling rubber dams more scientific and rational, and provided the key technical support for the construction of the extra-long filling rubber dam projects in the step development of Yihe and Shuhe rivers.
8.Abstract: To predict water-gushing is one of the principal problems faced in the surveying and designing extra-long tunnels.
9.The main operative complication was screw misplacement(7.1%), and others such as screw be nd and extra-long screw were less seen.
