Abstract:

The fusion efficiency of multi-sensor being theoretically proved to be better than that of any single sensor, analysis of groundwater macroscopic regime under a dam section was carried out by using a decision-making fusion method. As a result, following aspects can be identified.(1) The macroscopic regimes under dam section 9 had the tendency of increasing with time between 2003 and 2004, the close relationship with the reservoir water level; (2) The macroscopic regimes of section 9 kept close relationship with the reservoir water level from 2004 to 2007; (3) the anti-seepage performance of the curtain-grouting was to be weakened locally.

Key words: data fusion, error covariance, macroscopic regimes of dam foundation groundwater, durability of anti-seepage
