| Abstract: | From the constitution of anchor system, the influence of the interface strength between bolt and grout medium and between grout medium and soil or rock on of pullout resistance of fully grouted anchor was investigated. Then a formula for pullout resistance of fully grouted anchor was derived by considering the plastic zone developed on the interface between grout medium and soil or rock. Some conclusions were obtained in the practical application of the formula. |
