POTENTIAL OF GROUTING METHODS TO PREVENT AND COMPENSATE FOR TUNNELLING-INDUCED SETTLEMENT OF LONDON CLAY

Tunnelling beneath a congested urban area leads inevitably to the settlement of structures located in the ground above. In the past settlement has been allowed to take place and remedial work has been undertaken to make good any damage which has occurred. Grouting techniques have sometimes been used as a remedial measure to restore structures to their original elevation. Advances in grouting techniques, together with advances in monitoring, have led to the use of grouting in a compensation mode, whereby grout injection is carefully balanced against ground loss, such that settlement is not allowed to reach the surface. This method has been used in the USA and continental Europe, but so far has not been used in the UK. The development of grouting techniques used to remediate or compensate for ground settlement are reviewed and the results presented of a trial undertaken in London to investigate the viability of this technique.
