Stabilizing of High-altitude Position of the Centrifuge's Foundation by Compensation Grouting Technique During Underground Tunneling

The paper presents technique of regulated constructing elevation of buildings after their settlement because of tunneling under them. Control of buildings' elevation is based on preliminary calculation of grouting zones positions, injection sequence and injection volumes. Special software complex performs control functions over compensation grouting process, co-ordinating pumps work according to permanent horizontal and vertical monitoring of fundaments and correcting technological parameters of compensation grouting. Examples provide practical view on proposed technique.
