南京滨江大道沿线软土地基特点及软基处理对策

Soft Soil Foundation Features & Treatment Countermeasures to Route along Binjiang Ave. in Nanjing

南京滨江大道沿线地质条件复杂,地处长江漫滩地貌单元,线路区软土普遍分布。滨江大道高路堤较多,路堤的沉降与稳定,特别是"桥头跳车"在设计中必须予以重点关注。对滨江大道全线软土地质特点进行分析,并对软基设计的方法与特点进行介绍与总结。

Located in the landform unit of the flood plain of the Yangtze River,the geological conditions along Binjiang Ave.in Nanjing are complex,the soft soil in the line area is widely distributed.There are many high embankments on Binjiang Ave.,and the settlement and stability of the embankment,especially the bridge head jumpingmust be paid attention to in the design.The whole line geological characteristics of the soft soil in Binjiang Ave.are analyzed,and the methods and characteristics of the soft foundation design are introduced and summarized in this paper.
