Abstract

The NO.1 tunnel of YuanHeguan on the railway from Xiangfan to Ankang is a short-long railway tunnel. Design topic is the design for the NO.1 of Yuanheguan tunnel , the total length of the tunnel is 101m.

The plane section & vertical section of the tunnel are executed according to the engineering geology material. Based on the norm & the hole a standard diagram, the gate type of the tunnel is ascertained. The position of tunnnel portal and the pay line of tunnel are confirmed making use the method in diagram. The calculation of tunnel portal is proceed founding on the retaining wall principle, comprising the strength and

stability calculation of the wing & breast wall. Lining is designed according to the type and grade of tunnel surrounding rock, and its form is ascertained. The tunnel round the surrounding rock pressure is computed. The internal force of lining is proceed in the light of FORTRAN. Additionally, the strength of secondary lining is calculated grounding on the plait Fortran procedure. Based on the tunnel construction method and the material of the construction method, Step method is adopted. The construction organizes of the Yuanheguan tunnel is designed.

Key words: tunnel tunnel portal the designing of lining Excavate Construction
