| 摘 要： | 新规范《公路钢筋混凝土及预应力桥混凝土涵设计规范》(JTGD 62-2004)增加了有关桥梁结构耐久性的规定。凡影响混凝土耐久性,影响新老混凝土粘结强度,也必然影响桥梁结构的耐久性。通过对桥梁工程中新老混凝土粘结机理的浅析,对其粘结性能主要影响因素的分析,提出解决新老混凝土粘结问题的途径,从而提高结构的耐久性及可靠性。

| Abstract: | The regulations of structure durability of bridges are added to the new "Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts"(JTGD 62-2004).All that influenced concrete durability and the cohesion of old-to-new concrete must also have effect on the durability of the bridge structure.By simply analyzing cohesion mechanism of old-to-new concrete for bridge engineering,as well as main influence factor of bonding performance,the ways were proposed to solve the bond of old-to-new concrete.Thus durability and reliability of structure are improved. |

| Keywords: | durability old-to-new concrete mechanism of cohesion interface |
