Rock anchor foundation is an economy and advanced foundation form which is especially applica-ble for wind tower construction in mountain area. Installation of expansion anchor head at the bot-tom of full length grouted rock anchors can serve to reduce the anchorage length and increase pullout resistance of anchor system. Numerous groups of anchor rods have been tested to study the effect of anchor head on pullout resistance, including two anchor rods with expansion anchor head. The failure condition and limit pullout resistance of headed anchor has been analyzed with respect to different geological condition and different anchor length, comparing with the anchors without expansion heads. The measured values from the experiments have been compared with the calcu-lated values by the standard formula. It is concluded that, the anchor rods with expansion anchor head could satisfy the engineering precision and is applicable for wind tower foundation construc-tion.
