Study On Application Of The Counterfort Retaining Wall With Pile Foundation In The High Filling Engineer

In recent years, with the processing of the western development and the development ofurban construction rapidly, a large number of high fills are appeared in engineeringconstructions, therefore, how to support the high fill slope, become the main content ofengineering construction. And high fill slope with steep slope, high slope, fill volume, thetraditional retaining structure is difficult to solve the problems such as excessive lack offoundation bearing capacity and settlement of foundation soil.With the development of new type of retaining structure, Counterfort retaining wall withpile foundation, as a new retaining structure, absorbing the advantage of counterfort retainingwall and pile foundation, building up pile wall system, solve the problem such as differentialsettlement of the fill area and inadequate bearing capacity of the pile wall system. It can beused to bad soil slope support engineering and. Basing on the real project, discussing aboutthe pile caps counterfort retaining structure adopted on the unstable slope of high fill regionand doing research in the following areas:1) According to the project requirements and geological conditions, through the analysisand argumentation,taking the partition protection governance measures to the proposedsite,and then adopting the pile buttresses retaining wall to the platform area;2) Combined with practical engineering situation and through comparison and analysisof the Coulomb’s earth pressure theory and Rankine’s earth pressure theory, determine theactive earth pressure, then establish mechanical model of the calculation method of pile wallsystem, and research the retaining wall and pile foundation for the study as isolation body;3) According to the force characteristics of pile wall system, the twice reinforcement forretaining wall base plate; Consider the interaction of the pile and the wall, transfer the loads,when the isolation body do not meet the design requirements, to ensure the overall stability ofpile wall system;4) Combined with the simulation software, simulate counterfort retaining wall with pilefoundation numerically, and verify the numerical results with each other, justify pile wallsystem of the mechanical and the safety of design. This can provide preference for the designof similar projects.
