Abstract：Based on sheet-pile retaining wall and anchored anti-slide pile，the prestressed anchor sheet-pile is developed as a new type of retaining structures. On the basis of structure matrix method，combined with engineering characteristics，and with consideration of elastic restraint of anchorage cables，the relationships of earth pressure along with displacement，continuous conditions of displacement and internal force at preliminary shaft，and effect of anchorage part deformation on displacement of piles，stiffness matrixes of anchorage part and bearing part are established，respectively. Displacements and moments of metope pile，stresses and strains of anchorage part，and tension forces of anchor cables are all calculated by using a corresponding program. The calculated results have preferable regularity and agree with those of other methods，and this may be referenced in other related engineering projects.
