| 摘 要： | 对旧简支钢筋混凝土板桥,在加铺叠合层后的受力状况及承载能力进行了弹性和损伤分析。结果表明,加铺叠合层后一般可以使旧桥的承载能力提高50%以上,斜截面剪力提高70%;跨中挠度比原板要小;裂缝不会超过钢筋混凝土受弯构件最大裂缝宽度的1.05。

| Abstract: | The old bridge after reinforce ment with simple support was analyzed by elasticity and damage theory. The analysis results show that the capability of load of the bridge after reinforcement may be enhanced 50%,the shear may be enhanced 70%,the deflection was small than the old bridge, the cranny was not preponderated over 1.05 times of RC bending member. |
