Compaction Grouting Pack (CGP) Anchor which is composite anchor of bearing plus friction-type was chosen and executed for the open-cuts in soft ground. This paper presents an analysis of data from tests on composite-anchor by jacking force. The properties of composite-anchor was presented to be as follows , the maximum plastic displacement was 60 mm in abandoned coal fill deposit, the shear stress($\tau$) is expressed as $\tau$ = (equation omitted) kg/$\textrm{cm}^2$ in clayey silt.

The object of this study is to determine the application of friction and ground stress type CGP(Compaction Grouting Pack)-anchor in retaining wall construction on the soft ground by executing in the fill deposit with abandoned coal. In this study the effect of CGP-anchors as retaining wall anchor on the soft ground anchor was evaluated through measuring displacement according to tensile strength by acting tensile strength after equipping CGP-anchors. From the field tests results, CGP-anchor was determined to be considerably effective as retaining wall anchor on the soft ground by showing that the maximum displacement was 60mm and the elastic displacement was within 50mm by 53ton tensile strength.
