摘要
为解决城市桥梁桩基与地铁空间相冲突的问题,结合某项目跨涌桥与地铁结构空间相冲突实际案例,通过对常规桥台结构存在问题进行剖析,在此基础上设计了一种新型桥台结构。进一步通过对新型桥台结构进行数值分析计算,验证了该结构构造合理、安全可靠,较好地解决了桥台桩基与地铁结构空间相冲突的难题。另外,根据新型桥台设计理念的延伸与拓展,提出了其它两种桥台形式,这些新型桥台结构对于桥梁与地下空间有避让需求的类似工程都适用,实际工程中可以根据地下空间需要选用相应的结构形式,具有较大实用参考价值。
In order to solve the conflict of urban bridge pile foundation and subway space,designs a new type of bridge structure based on analyzing the problems of conventional bridge structure.Through the numerical analysis and calculation of the new abutment structure,it proves that the structure is reasonable,safe and reliable,and the conflict between the abutment pile foundation and the subway structure space is better solved.In addition,according to the extension and expansion of the new abutment design concept,put forward the other two abutment forms,these new abutment structure for bridge and underground space to avoid similar engineering,the actual engineering can according to the lower space need to choose the corresponding structure form,has great practical reference value.
