Abstract:

Due to the complex geological conditions, rich ground water, great construction difficulties in the site or some other unexpected factors, the quality of some shielddriven tunnels fails to reach the expected targets. By means of analysing the reasons for such quality defects as water seepages, segment offsets and damages of segment corners that have occurred in Shi~Pan shield driven tunnel, the article summarizes the prevention measures for the quality defects of shielddriven tunnels.
