| 摘 要： | 预应力锚索技术普遍存在设计保守和支护效果不佳的问题，不仅造成工程浪费，而且阻碍自身发展。本文提出了预锚设计分级优化的概念，通过研究初级优化原理，统一说明优化参数的定义、关系和设计敏感度，并提出优化评估指标，以此初步探讨了预锚优化设计统一理论。

| Abstract: | Prestressed anchor cable technique faces the problems of conservative design and dissatisfactory effect,leading to over-consumption in engineering and going against the further development of the technique.Optimized design methods of prestressed anchor cables came forth at that time,which aren't unified up to now.The concept of grading optimized design is suggested in this paper.Besides evaluation indexes of optimization,unitive definitions of the main optimized design parameters and analysis of their connections as well as design sensitivities are proposed by discussing on the theories of first grade optimized design.All of the results mentioned above can make up the main frames of the unitive optimized design methods of prestressed anchor cables. |

| Keywords: | prestressed anchored cables maximum sliding resistance economical anchoring angle first-grade optimized design evaluate indexes of optimization |
