Abstract

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.
