摘要
介绍一种采用“桥路一体化设计”的新方法 ,即在桥梁设计中采用无台身钢筋混凝土实体桥台及在桥墩上设置可升降式支座的措施来防止桥头跳车 ,这种方法较好地解决了桥台和台背路基填土的刚柔过渡问题 ,消除桥头部位在通车以后产生工后不均匀沉降 ,较彻底、简便。
The paper introduces a kind of new methods used “integration design of bridge and road”, i.e. in design of bridge the reinforced concrete solid abutment without abutment body is used and the lifting support is installed at bridge piers to prevent jumping at bridge head. This method solves the problem of rigidity and flexibility transition of subgrade filling at bridge abutment and bridge back as well as eliminates uneven settlement of bridge head position after construction and after the traffic and solves thoroughly, simply and rapidly the jumping problem at bridge head.
