The Retaining Structure Work Character Analysis Of Double-row Piles

As a new retaining form, double-row piles structure， particularly compared withthe single row soldier Pile, has many advantages;such as excavate more conveniently,low demands on environmental construction of foundation pit，save the project cost andshorten the construction period. All this just because double-row piles structure has ahigher lateral stiffness, which could control the construction duration effectively.Butuntil now, the design and the calculation method of double-row piles retainingstructure is not mature.The existing calculation method is hard to reflect the stressmechanism of double-row piles structure. Based on the actual engineering of retainingstructure with double-row piles and anchor pile of the measured deformation analysis,theoretical analysis and finite element numerical analysis. And the main researchcontent is as follows:Summarize the research status of double-row piles structure and the researchsituation. At the same time analyzed several typical research results and explain theadvantages and disadvantages about them.Measure the actual project supporting structure，analysis the measured results.bycombining existing specification method with the finite element numerical method andother theoretical method.Analysis the anchor pile support structure work character anddouble-row piles.Use theoretical analysis and finite element numerical method，in view of theretaining structure with double-row piles researches on the effect between the front rowpile and the back row pile.Base on this，using finite earth pressure theory to analysis thestess and deformation characteristics of double-row piles. According to change some parameters，such as the row spacing，stiffness of the linkage and the diameter of the pile，to analyze the influence of the stress and deformation.
