Abstract  Based on the literature numerical modeling type II(2D),a three-dimensional dynamic compaction model considering different load widths is proposed and verified. At the same time,a calculation formula of compaction stress retaining wall considering Chinese norms was introduced,and the three-dimensional dynamic load moving mode was discussed. First,through the selection of equivalent load loading method,the influence of different load widths on the retaining wall is discussed according to the strain of the reinforcement,the lateral deformation of the panel,the soil pressure behind the wall and the compressive stress distribution of the base. And the depth of compaction stress is used to provide verification for the calculation formula. The analysis shows that the calculation method of the equivalent load movement method is closer to the measured value than the second and third methods;the strain change trend of each layer is basically the same,showing two peaks,the first one is located at the back of the panel,the second place Peak load point due to shear strain concentration(potential fracture surface);the type of compaction modeling does not affect the distribution of vertical compressive stress at the bottom of the wall;only when the additional load of the retaining wall exceeds the compaction load,the compaction stress the effect will dissipate. At the same time,for different compaction stresses,ribs and soil properties,the corresponding compaction depth is also different;The strip load width(B) has obvious impaction on the internal stress prediction of the retaining wall.
