| 摘 要： | 本文介绍了c筋在预应力混凝土公路梁桥建设中的应用。该桥为整体现浇25m跨径简支梁,采用CFRP筋中的碳绞线(Carbon Fiber Composite Cable)作为体外预应力束。文中论述了设计中应关注的主要问题,运用理论方法和有限元方法对结构作了全面分析,并在造价上与普通预应力混凝土梁桥作了比较。 |
| 关 键 词： | 桥梁 预应力混凝土 CFRP 体外预应力 |

| Abstract: | The application of Carbon Fiber Reinforced Polymer(CFRP)tendons to prestressed concrete highway bridge is addressed.The bridge consists of 25m-long simply-supported monolithic concrete girders external prestressed with Carbon Fiber Composite Cable(CFCC),one type of CFRP tendons.The main problems which should be paid at- tention to in the design are thoroughly discussed;the structure is analyzed with related theories and finite-element methods.The differences in cost between this bridge and ordinary prestressed concrete bridge are described. |
| Keywords: | Bridge Prestressed concrete Carbon fiber reinforced polymer External prestressed |
