Abstract：Research purposes: With the increase of the underground projects in cities，as a new patent technology，the recuperative anchor is gradually applied to the bracing system of foundation pit． As the common prestressed anchor is often non － recyclable，only in Guangdong and Beijing there are thousands of tons of steel cable to remain in the ground one year． This not only causes the big material waste，but also becomes the obstructions for follow － up construction and causes the underground pollution． The cable which is ramped into the pit usually intrudes the underground space of the building nearby as it extends the contruction line．
Research conclusions: By taking the successful application of recuperative anchor in the Futian Hub project of Shenzhen metro as an example，this paper introdues the technical requirements and matters that need to pay attention to in application of recuperative anchor in a given project． From the long － term view，the application of recuperative anchor will not only considerably saves the production cost of enterprise，but also reduces the influence on the surrounding environment，saves energy and benefits the society．
