| This text introduces a new type of slope support structure -- self-balanced composite retaining wall, raised the subject of the present study less -- inclined pile of fixed length. On this basis, this study proposes a design of inclined piles of fixed calculation.Through reading extensively and analyzing synthetically of the relative document both domestic and abroad, the text carries through systems analysis and introduction of dynamics character and analysis computing method of the foundation pile under horizontal load. On this basis, made a number of calculated assumptions, respectively, in the"K"method,"m"method, the derived length of rigid piles embedded solid formula and formula for calculating the internal force of elastic pile,and put forward the calculation method of fixed length basised on the stability of the soil body at the former of batter pile.The article used a large-scale finite element analysis program, applied finite element analysis of the self-balanced composite retaining wall. Adopting D-P yield criterion, define the appropriate material parameters, building self-balanced composite retaining wall models to meet the requirements of analysis, and mainly discusses the function of the inclined direction and the obliquity of the pile shaft to the batter pile horizontal bearing capacity. The formula and result of numerical analysis is agreement with theoretical analysis result. |
