Abstract
The stress and deformation of the pile-plate retaining wall in the construction process of highway slope is numerically calculated,and the stress and deformation characteristics of the pile-plate retaining wall are found out by the finite element software Midas GTS NX.The results show that the horizontal displacement of the sheet-pile wall pile body decreases with the increase of the distance from the pile top.The variation range of the cantilever sec-tion is greater than that of the anchorage section.And the horizontal displacement of the pile top increases with the increase of the filling height;After the pile filling,the pile body is in a state of compression.And the axial force in-creases first and then decreases with the increase of the distance from the pile top;With the increase of the distance from the pile top,the shear force of cantilever section changes in S-shape,and the maximum value occurs at the junction of the anchor and the cantilever sections.The shear force of the front section of the anchor section changes little,and the shear force of the back section increases with the increase of the filling height;The bending moment increases first and then decreases in the upper part of the cantilever section with the increase of the distance from the pile top,and changes sharply when it is close to the ground.In the anchorage section,it shows S-shaped variation with the maximum value at the junction between the cantilever and the anchorage sections;When the filling height is lower,the bending moment of the cantilever section is zero.The bending moment of the anchorage section gradu-ally changes from left compression to left tension with the increase of filling height.关键词
