摘要
总结了预应力混凝土结构的发展史 ,阐述了预应力混凝土的原理和优越性 ,并通过实例 ,提出了有粘结预应力在钢筋混凝土井字梁中的应用情况 。
Combined with the development of prestressed concrete structure the principle and superiority of prestressed concrete are elaborated. And through actual example the application of bonded prestress in reinforced concrete crosswise beam is introduced. At last the prospect of reinforced concrete prestressed engineering is expected.
