The theoretical proposed approach is simplified to be used for practical purposes. The results show that if the stiff end plate is tightened to the bolt head (complete planner contact), the grouting effect of the pretensioned fully grouted bolts on tunnel stability can be neglected.
HMS Sutlej was a Cressy-class armoured cruiser built for the Royal Navy around 1900. Upon completion she was assigned to the China Station.In 1906 she became a training ship for the North America and West Indies Station before returning home and being assigned as the flagship of the reserve Third Fleet in 1909.
