Title:	Geological and logistical challenges of the TBM drive of the Pinglu Tunnel in China / Geologische und logistische Herausforderungen beim TMB-Vortrieb des Pinglu Tunnels in China
Abstract:	The 25 km long Pinglu Tunnel is part of a large water supply project in the north west of the Chinese province of Shanxi. After a brief description of the overall project, the article describes the alignment, geology, lining and the TBM and machinery concept. A second-hand hard rock double shield machine built in 1994 was supplied by the employer and had to be overhauled for the reject. During the progress of tunnelling, numerous mechanical, logistical and geological challenges had to be overcome. Der 25 km lange Pinglu-Tunnel ist Teil eines großen Wasserversorgungsprojekts im Nordwesten der Provinz Shanxi/China. Nach einer kurzen Gesamtprojektübersicht beschreibt der Beitrag die Trassenführung, die Geologie, das Ausbaukonzept sowie das TBM- und Gerätekonzept. Zum Einsatz kam eine gebrauchte Hartgesteins Doppelschild Maschine aus dem Jahr 1994, die vom Auftraggeber bereitgestellt wurde und vom Auftragnehmer für das Projekt aufgearbeitet werden musste. Bei dem Tunnelvortrieb gab es zahlreiche maschinentechnische, logistische und geologische Herausforderungen zu meistern.
