梅龙高速公路深度3号桥梁体滑移纠偏施工

Slip Correction Construction Method of Deep No.3 Bridge of S12 Meilong Expressway

S12梅龙高速公路K24+615深度3号桥2014年通车运营后,在车辆动荷载及梁体本身纵向下滑力的作用下,第一联(0#~5#墩)左幅梁体向梅州方向纵向位移5~7cm,右幅梁体向梅州方向纵向位移3~5cm,影响行车安全。通过对第一联偏移梁体整体顶升和对支座进行改造后,同步顶推纠偏使梁体恢复到原设计位置。

After Shendu No.3 Bridge at K24+615 of S12 Meilong Expressway was opened to traffic in 2014,under the action of the vehicle dynamic load and the longitudinal sliding force of the beam itself,5~7cm longitudinal displacement of the direction to Meizhou appeared at the first joint(0#~5#pier)left beam,and the longitudinal displacement of the right beam body to Meizhou is 3~5cm,which have affected the safety of traffic.After reconstruction of bearing with whole lifting of the first joint beam,the synchronous thrust correction has restored the beam to the original design position.
