荷载对铺装层应变的影响

Analysis of the Deck Pavement on Steel Box Bridge

通过计算不同荷载大小及位置条件下铺装层中出现的最大正负应变 ,分析这些因素对铺装层中顶面应变的影响程度 ,得到荷载作用的最不利的位置。对荷载大小的影响也进行了计算 。

In this treatice,the pavement is analized from the angle of box,using the tool of finite elements,the position of the load which makes the largest strain has been confirmed And this position can be used for design The development trend of strain with loading has been analysed quantitatively. And the result is useful to actual work
