摘要
庆淄路惠青黄河公路大桥为部分斜拉桥,矩形桥塔,塔梁墩固结,桥塔处主梁设置有斜向横隔板。建立其塔-梁-墩固结部位的三维有限元模型,分析该部位的局部应力。重点分析桥塔作用在主梁上的荷载对0号块主梁应力的影响,以及竖向及横向预应力荷载的效应。
The Huiqing Huanghe River Highway Bridge at Qingzi Road is an extradosed bridge with rectangular shape pylons, rigid fixity of the pylons, girder and piers and with inclined diaphragms arranged in the main girder nearby the pylons. In this paper, the three-dimensional finite element model is established for the part of the rigid fixity to analyze the local stress at the part and particular efforts are made to analyze the influence of load action from the pylon to the main girder on the stress of segment No. 0 of the girder and also the effect of vertical and lateral prestressing load.
