Study On The Application Of Prestressed Anchorge Sheet Pile Retaining Wall

Prestressed anchorage sheet pile retaining wall is a new type of light-retaining structure.It has already extensively been applied in highway, railway and water electricity etc.As a highway embankment's shoulder or Slope retaining structural,It was very widely applicated.but the theory of the structure still can't meet the need of application.To study the interaction mechanism of it with theoretical analysis,numerical calculation,Prototype tests,and other methods,This study has important significance for the engineering aplacation and theoretical value.According to the present research status of prestressed anchorage sheet pile retaining wall,With the project "Research on retaining wall structure in mountain area " and Prestressed anchorage sheet pile retaining wall's application,the following conclusions can be drawn:?Considering the process of Construction the status of the dynamic design method is a more reasonable method of calculation.The condition can be divided into filling conditions(recorded as A mode),cable-strench condition(recorded as B mode).?Based on the assumption of Winkler beam on elastic foundation,the theory of finite difference model can be calculated several different to the grassroots,variable cross-section pile internal forces,and the corresponding computer program was developed, compared to the initial parameter method and triangonometric series,its design and calculations are more reasonable,convenient,flexible.?Anchor in pile, anchor limited the displacement and adjustment of the distribution of bending moment effects,due to anchor location in pile and anchor tensioning timing and foeces on the size.?the application of Anchor on the piles changes the distribution of earth pressure and size,according to the field measured bending moment and displacement,through the back analysis method to study the status of earth pressure distribution and size,and with the measured earth pressure comparative analysis come to different earth conditions pile earth pressure on the pile and sheet force distribution rule.?The design and construction technology are introduced,Fill some of which anchor the method by filling and anchor construction sequence can be divided into three types:anchor after finished filling, fill when anchor finished and fill while anchoring.?The failure mode can be divided into four mode,such as failure of connection with the pile and anchorage, anchorage failure,pile destruction and total failure.Basing on research on prestressed anchorage sheet pile retaining wall design calculation method and internal forces pile,earth pressure distribution rule,To provide design and construction of reference,further guidance on the practice.
