【Abstract】 In this paper, the basic theory applied in the current design method of reinforcing systems of prestressed anchored steel rope is analyzed, and it is suggested that the key to the improvement of the design method is to enhance the knowledge of the reinforcing mechanism and effect. After analysis of the features of prestressed anchored steel rope systems, several comments are made on what are important problems in the study of such systems and how the reinforcing effect can be improved. The problems of how to apply the finite element method to calculate such systems, and how to calculate and study a large system consisting of a group of prestressed anchored steel ropes are also discussed.更多还原
