Study On The Application Of Overall Cast-in-situ Prestressed Anchorge Sheet Pile Retaining Wall

In the western region, there are steep peaks, complex terrain, high mountains and deep valleys. especially in Yunnan.To build roads in the deep valley or steep cross slope, Often need to adopt new high retaining wall. using a new high retaining wall across the excavation surface is small, second, are available consumption of waste earth and made a security, economic and environmental role.Prestressed anchorage sheet pile retaining wall is a new type of light-retaining structure.Currently, it has already extensively been applied in highway, railway and water electricity etc.Overall in-situ-type anchor pile wall is a kind of anchor pile wall in order to anchor the main force.The structural use of lightweight design,and the structure size is small,concrete amount is small, and easy to continuous pouring of concrete construction, which can effectively shorten the construction period and lower project cost.However, this type of retaining structure has not yet formed mature design and calculation methods.In this paper, the main researches work are:1,On the existing pile and wall method are summarized, based on elastic foundation theory, the finite difference method, and programmed using Visual Basic to solve pile and wall force;2,Through a mountainous area of Yunnan Expressway K117 work the whole point of Prestressed Concrete Pile Retaining Wall Anchor Structure of physical prototype testing of engineering systems, the measured Anchored Retaining Wall in the condition of the internal forces and filling Earth pressure analysis;3,The experimental study on the basis of the overall structure of Prestressed Concrete Anchored Retaining Wall in the condition of the mechanical characteristics of the proposed retaining structure of the calculation model and verify its reliability, the design method improvements provide a reference.
