In recent years, China's high-speed railways, expressways, ordinary road railways, intercity railways, underground railways and many infrastructure projects have increased a lot, and the use of prestressed concrete structures has continued to grow rapidly. The production and supply of prestressed tension anchoring system has increased greatly, of which the largest use is prestressed steel strand and clip anchorage,2009 and 2010, China produced 150 million holes a year clip anchorage, far more than European and American countries. However, there are still some problems that should be solved, such as: the ease of use of prestressed steel strand should be improved, the size of the anchor kit (anchor plate, spiral bar, etc.) should be returned to the scientific level, the overall view of the efficiency coefficient of the anchor, and to ensure the safety of the prestressed reinforcement anchorage area in the structure is the most important problem at present. The current situation in China has required the load transfer test to be included in the national product standards. In this period of great development of prestressed engineering, the Concrete and Prestressed Concrete Branch of China Civil Engineering Society has always paid close attention to the performance of prestressed tension anchorage system in engineering practice.
