The Design And Application Study Of The High Counterfort Retaining Wall

In Chain,with the rapid economic development and civil engineering increasing，Projects need to be built in the mountains whose terrain is relatively large. A larguenumber of embankment and excavation slopes that height is10m~25m will oftenencounter in actual project. In order to meet the needs of industrial production andmore efficient use of land resources, save area of land.Using of high retaining wallhas very good practice significance. The main content of this article has the followingthree aspects:Frist, calculate passive and active earth pressure on high counterfort retainingwall.Selecting commonly used Rankine or Coulomb’s earth pressure theory combinedwith applicability of high retaining wall and earth pressure theory to calculate earthpressure. According to the information model test and field test at home and abroad,using coulomb theory with the second failure surface method for calculating lateralearth pressure is more in accordance with the actual. Imaginary parados method couldbe used to calculate lateral earth pressure when the second failure surface can’t beformed. In engineering applications, lateral earth pressure acting on retaining wallcalculated should be based on the specific forms of retaining wall and nature of soilbehind the wall. When it is difficult to determine the actual works in either case,Separate analyses of situations to cope with potential calculation and take the mostnegative of lateral earth pressures as a design value.Second, components of the high counterfort retaining wall calculation.Analysis and calculation overall stability of high counterfort retaining wall.Select calculation model of components of the high counterfort retaining wall tocalculat, reinforce and check crack width.Third, numerical model and optimization design.By Phase2D slope of finite element software for the model of two-dimensionalgeological, simulation support side slope stability and deformation characteristics. Bychanging the size parameters to optimize a retaining wall design.And noted that thestudy of issues related to high buttressed retaining wall.
