“路归路、桥归桥”问题的探讨

Study on"Road is Road,Bridge is Bridge

分析了温州地区桥头跳车的主要原因 :桥台后路基沉降及桥台后地基沉降 .介绍了几种预防和修复的技术措施 ,即从路基处理入手可以考虑减轻填料重量、优化设计、加强施工工序的管理和改进机械设备 ;从解决地基沉降量着手可以考虑选用轻质填料 ,采用真空堆载预压法 ,采用水泥搅拌技术 ,采用喷浆技术 ,加强施工质量管理 .

It is explained why the vehicle pitch at bridge approach in Wenzhou.The reason is mainly in two sides:the roadbed and the foundation subsidence behind the abutment.Several precautionary and repairment technique measures are put forward.In the side of roadbed treatment,reducing filling weight,changing design,tighten up the management of construction order and updating equipment are introduced.In the side of reducing the volume of foundation,using light weight filling,vacuum heaped load prepress,cement injection pile,the technique of spraying cement mortar,tighten up the quality management are considered.The engineering examples of Wenzhou are also proposed.
