摘要
针对常用的桥面连续构造形式,给出了桥面连续构造内弯矩及应力计算方法,并对一6×20m空心板桥桥面连续构造进行了计算分析。结果表明:桥面连续构造内应力主要由竖向活载引起,汽车制动力及温度作用引起的应力很小。
Calculation method of moment and stress was given for deck consecutive structure which is frequently used and the deck consecutive structure of 6-20m slab-bridge was calculated and analyzed. The results show that: stress is mainly caused by vertical live load, automotive braking force and temperature caused little stress in deck consecutive structure.
