The Design Of Inclined Plug-in Zhuangbanqiang Theory And Application Research

Sheet-pile retaining wall is one of the new-type supporting structure of the support.The traditional retaining plate is a vertical plate, and it cannot be combined with green measures. Sheet-pile retaining wall with inclined plate in recent years combining greening measures appeared a new-type of sheet-pile retaining wall structure.But the literature study on the design of sheet-pile retaining wall with this inclined plate is so poor. Aiming at inclined plate’s design theory, this paper will research and analyse the inclined pile retaining wall’s earth pressure distribution regularity of stress and structural stress system.At first, papers establish three dimensional spatial model through MID AS.Then papers analyse earth stress of sheet-pile retaining wall with inclined plate on the basis of the traditional sheet-pile retaining wall’s force analysis and calculation of earth pressure. And then it sums up the distribution of earth pressure for non-linear increasing trend.Papers propose a modified method of construction technology of inclined plate on the basis of the traditional straight plate. Papers use finite element method to analyse the effect of the lateral earth pressure of wall back responding to inclined plate’s angle, piles and straight plate spacing parameters. It optimize the design of sheet-pile retaining wall with inclined plate’s structure combining the engineering with economic, and demonstrate that the best angle of inclined plate is40°. At last it introduces construction method of the general pile wall greening of the Wall,and makes the imitation of natural-pile wall and natural stone-pile wall concept.
