Abstract To understand the structural behavior of geogrid reinforced soil retaining walls (GRSW) with a deformation buffer zone (DBZ) under static loads, the model tests and the numerical simulations were conducted to obtain the wall face horizontal displacement, vertical and horizontal soil pressures, and geogrid strains. Results showed that compared with the common GRSW, the horizontal displacement of GRSW with DBZ decreased, and the horizontal soil pressure acting on the face panel of GRSW with DBZ increased. The vertical and horizontal soil pressures showed a nonlinear distribution along the reinforcement length, and the value was smaller near the face panel. The horizontal soil pressure acting on the face panel of GRSW with DBZ was greater than that of the common GRSW in the middle portion. The cumulative strain of the geogrid had a single-peak distribution along its length; the maximum strain of the geogrid was 0.45%, the maximum tension was approximately 29.12% of ultimate tensile strength.

带变形缓冲区的土工格栅加筋土挡土墙静结构性能

摘要 为了解带变形缓冲区（DBZ）的土工格栅加筋挡土墙（GRSW）在静荷载作用下的结构行为，通过模型试验和数值模拟，获得了墙体面水平位移、垂直和水平土压力，和土工格栅应变。结果表明，与普通GRSW相比，含DBZ的GRSW水平位移减小，作用于含DBZ的GRSW面板的水平土压力增加。垂直和水平土压力沿配筋长度呈非线性分布，在面板附近值较小。作用于带 DBZ 的 GRSW 面板的水平土压力大于中间部分普通 GRSW 的水平土压力。土工格栅的累积应变沿其长度呈单峰分布；土工格栅的最大应变为0.45%，最大拉力约为极限抗拉强度的29.12%。
