Combined with low cost of concrete cylinder pile and good flexural performance of steel tubular pile,the flexural capacity of the steel-concrete composite pile’s upper part is equivalent to steel tubular pile,to a certain extent,making up for the application bottleneck of large-diameter prestressed concrete cylinder pile’s flexural capacity,under the premise of meeting the project quality requirements and achieving the purpose of reducing costs.combined with the engineering example,the paper analyzes the design method,drivability and the comprehensive economic cost of steel concrete composite pile,which provides reference for the application of steel concrete composite pile.
