| 中文摘要: |
| 门架式桥墩在城市立交桥中应用越来越广泛,文章针对深圳兴海月亮湾立交匝道桥中的门架式桥墩进行建模计算,得出其受力和变形情况.针对计算结果中可能出现的应力集中问题和帽梁的开裂问题,分别采用构造措施和预应力分批张拉以及调整施工工序的方法予以解决. |
| 英文摘要: |
| App1ication of gate posture pier in the urban multi-lever crossing bridge is becoming more and more widespread.Aiming at a gate posture pier of the Xinghai crossroads in Shenzhen,a 3-d model is established to analysis its stress and the distortion situation.In view of the stress concentration question in the calculation result and cap-beam cracking question,the method of structure measure as well as batched stressed of pre-stress stell and adjusting the construction working procedure are proposed respective... |
