Abstract:

A great amount of monitoring data were obtained during the grouting reinforcement process in vertical shaft; and then several specific non-dimensional impact fatcors were educed from these original test data.Using nonlinear least square approximation method, the relation between the vertical strain change of arbitrary position on the shaft lining and the given grouting phase was reached. The analysis result shows that not only the relative space location between grouting place and monitoring point, but also the grouting pressure and injected amount affects this vertical strain change nonlinearly; and that vertical relative location has the more prominent affection.

Key words: soil grouting, vertical shaft, monitoring, data analysis
