Abstract

Abstract:

The nondestructive monitoring of gravel filling effect of foundation of immersed tunnel timely, economically and effectively is a key problem to be solved. The impact imaging method used in gravel filling effect monitoring of foundation of Honggu Tunnel is systematically introduced in terms of monitoring line arrangement, data collection, analysis and assessment and suggestions. The monitoring results show that impact imaging method is feasible and effective in monitoring gravel filling effect of immersed tunnel foundation.

Key words: Honggu Tunnel, immersed tunnel, foundation gravel filling, impact imaging method, monitoring
