Abstract: The nonlinear relationship of lateral displacement and nonlimit internal friction angle was introduced. By the stress relationship between inclined wall back and sliding cracking surface under nonlimit state and the horizontal static equilibrium equation of horizontal micro sublayer unit, the nonlimit slide cracking surface inclination was obtained and the nonlimit active earth pressure calculation formula for inclined rigid retaining wall with soil arching effect under translating mode and the displacement considered. The parameter analysis results indicate that the increase of lateral displacement proportion causes the increase of inclination of nonlimit sliding cracking face, decrease of nonlimit active soil pressure coefficient and decerase of nonlimit active soil pressure. The increase of inclination of wall back causes the decrease of inclination of nonlimit sliding cracking face, decrease of nonlimit active soil pressure coefficient and increase of nonlimit active soil pressure. The nonlimit active soil pressure decreases with the increase of internal friction angle of filled soil and wall soil friction angle. Compared with traditional method the proposed nonlimit active soil pressure theory value fits better experimental values.

摘要： 引入非极限内摩擦角同侧向位移的非线性关系；根据非极限状态下的倾斜墙背与滑裂面上的应力关系，以及水平微分层单元的水平静力平衡方程，得到了非极限滑裂面倾角，进而得到平移模式下考虑土拱效应和位移影响的倾斜刚性挡墙非极限主动土压力计算式。研究表明：侧向位移比的增大使非极限滑裂面倾角增大，非极限主动土压力系数减小，非极限主动土压力减小；墙背倾角的增大使非极限滑裂面倾角减小，非极限主动土压力系数减小，非极限主动土压力增大；非极限主动土压力随着填土内摩擦角、墙土摩擦角的增大而减小；与已有方法比较，提出的非极限主动土压力理论值与试验值吻合得更好。
