Most often, the effect of anchor installation on the ground movements is ignored. This paper, however, reveals that this effect will be considerable in soft clays if appropriate drilling technique and support for the drill hole is not used. A case history shows that more than 70percent of the total ground settlement had occurred at the surface during the anchor installation. An attempt is made to back analyses the effect of anchor installation on the ground movement with the help of finite element method and analytical approach.
