Abstract：Removable anchor technology, which has developed rapidly and been applied to foundation pit projects in recent years, may avoid those problems of underground obstacles and infringement associated with the non-removable main reinforcement. In this work, the application background of removable anchor technology and the development process of removable anchor technology and relevant standards at home and abroad were reviewed and summarized, the types of removable anchor were categorized, and the configuration and removable mechanism of removable anchor commonly used were elaborated, and then the issues deserving attention in the applications of removable anchor technology were put forward. Finally, based on the application status of removable anchor technology, some suggestions on its research and development direction were given.
