The characters and application foreground of concrete-filled steel tubes
It points out the steel tube concrete structure can make good use of two materials of steel tube and concrete and has other merits such as high strength,light weight and good seismic performance.In the paper the character's research situation and engineering application of concrete-filled steel tubes are introduced.The research direction of concrete-filled steel tubes is discussed,so as to extend the structure,in order to promote the application of the steel tube concrete structure.
The paper introducess the implemented conditions which colling recycle of flexible base on Ying-DaLine.It over all xpounds the investigation of road condlitions of original pavement,indoor trial study,determination of trial lot plan as well as completion of trial lot etc.
