Rammed Soil-Cement Pile And CFG Pile Composite Foundation Characteristics Research

In recent years,China has invested a lot of energy and material resources in ourinfrastructure,architectural forms show the diverse,construction technology isbecoming more and more difficult.people are compelled to carry out technicalinnovation.The cement pile and CFG pile composite foundation get rapiddevelopment and application in this new situation and environment.In order to understand the working mechanism and the engineering properties ofthe tamped concrete pile and CFG pile composite foundation more clearly, theTamped concrete pile and CFG pile were contributed to a certain amount of theoreticalresearch, and finally design parameters of the combined pile composite foundation arerelated study by the numerical simulation.Based on the above analysis and simulation research,the research result can bebroadly grouped into the following aspects:Firstly, the engineering properties of tamped concrete pile and CFG pile arediscussed, and give bearing capacity and settlement formula that suitable for use inengineering.Secondly, two types of piles are studied in this article. This article focuses on theworking mechanism and its bearing capacity and settlement calculation and gives theformula to be used for engineering of two types of piles composite foundation.thismethod is proved to be correct by project.Thirdly, this article use the ABAQUS to set up numerical finite elementsimulation, the three-dimensional model is established, the combined pile axial forceand the pile-soil-sharing ratio are discussed of Cushion parameter changes and underdifferent loads.The article has carried on certain research discussion regarding the engineeringproperties of compacted cement pile and CFG pile composite foundation, and it wasconfirmed in the practicality of the project. It is a preferred ground-based approach.
