摘　　要：阐述了体外预应力结构的概念与特性 ;系统地论述了体外预应力结构设计中应考虑的问题 ,包括预应力筋线型布置 ,正常使用和承载力极限状态下的内力分析 ,预应力损失计算方法 ,转向块和局部承压区设计 ,以及耐久性。The concept and features of externally prestressed concrete structure are expounded.The design method of externally prestressed structure are systematically illuminated,including the tendon profiles,analysis of internal force at both the serviceability and ultimate state,the evaluation of prestressing loss,the design of deviator and local bearing capacity.Durability and fire resistance problem are also considered.By doing the above work,a foundation is laid for this new structure to be popularized and applied in our country.

关 键 词：体外预应力结构 结构加固 预应力损失 转向块 耐久性
