Commentary on Soft Ground TBM Tunnel Face Support Calculation Methods

연약지반 TBM 터널 막장지보 계산방법 해설

Abstract

The German Tunnelling Committee (DAUB) recently published new recommendations for face support calculations; Zdenek Zizka and Markus Thewes of Ruhr University Bochum actively discuss and explain these new recommendations where these recommendations are intended to assist in choosing between various calculation methods which are also dependent on ground conditions. The guidelines also discuss important scientific approaches with face stability calculations, mainly those due to earth pressure and groundwater pressure on the tunnel face. This paper aims to explain these recommendations through Zdenek Zizak and Markus Thewes's discussion on these Tunnel Face Support Calculation Methods.
