Structural Design of SHAKPAKBABA – the First Tunnel of KAZAKHSTAN (In International Transport Corridor)

Shakpak Baba Tunnel Project is located in the vicinity of Shymkent city along the international transportation corridor of Khargvs-Almaty-Shymkent in kazakhstan to Uzbekistan border. The project deals with construction of two main tunnels and adits connecting them to one another. In this paper, the structural analysis of tunnel lining is presented. Numerical analysis of the lining was performed with UNWEDGE DEM Software. Behavioral parameters adopted for structural design process are moment, shear and axial force as well as deflections.
