TILT RECTIFICATION OF WELL FOUNDATION - A CASE STUDY

The construction of well foundations in the bouldery beds of continuously flowing rivers was investigated on a bridge in NE India. The river depth varies between 7.8m and 15-18m, with a flash flood around April/May and it remains in spate until about the end of October each year. The diversion of the river is not possible. During construction of the well foundations in April 1991 there was a sudden rise in water levels and this combined with the monsoon period caused the over-tilting of one of the well foundations. The design and layout of a rectification scheme is described. It was planned to pull the well horizontal using prestressing and this was successfully achieved. There was an urgent requirement to add additional steining after rectification of the tilt because of high rainfall.
