Abstract：Prestressed ground anchor has been used widely in all kinds of geotechnical engineering reinforcement such as hydropower，highway，railway，mine and city planning etc.，and remarkable economic and society benefits have been achieved with ground anchor reinforcement in these fields. Now ground anchors have become the main method in these engineering reinforcements. But，there is hardly literature report and engineering practice about prestressed anchor cable used in rectification of foundation. The west gate of GuoHua Garden in Luoyang city is mainly a steel structure，with total weight of 600 kN. The soil conditions underlying the bases are fills in the range of 7–8 m in the depth，which are mainly composed of clayey silt and a little building waste. Non-uniform settlement of the ground has appeared since the west gate of the garden was built because of not compacted of foundation soil during the ground treatment. Prestressed ground anchors have been used successfully in the rectification and reinforcement. The practice shows that prestressed anchor cable technique can play unique advantage in rectification of foundation，offer reference for similar engineering，and find more application range.
