Mechanical performance of a double-face reinforced retaining wall in an area disturbed by miningAbstract: The application of a double-face reinforced retaining wall during road construction can reduce engineering costs, speed road paving and have a good influence on environment. An ABAQUS numerical model of a double-face reinforced retaining wall was built. The influence of surface subsidence induced by mining was considered. A physical model test was also performed in the laboratory on a reinforced retaining wall. The influence of subsidence induced by mining was observed. The numerical results match measurements in the laboratory very well. The vertical pressure on the base of the retaining wall, the horizontal displacement of the wall and the horizontal soil pressure acting on the wall were analyzed. The differential settlement of the reinforced belt and axial forces in the wall were also studied.Keywords: double-face reinforced retaining wall; underground mining; finite element method; physical model testIntroductionThe road surface above a mining area will subside due to the work underground. Directly backfilling soil before sloping was adopted to reduce the influence of mining on surface roads. This method usually wastes land and is not reasonable economically. A doublefaced reinforced retaining wall does not need conventional sloping and therefore saves land. With mining, the road can be elevated using a double-faced reinforced retaining wall[11.Many scholars have carried out preliminary studies on double-sided reinforced retaining wallst2~8]. Lei studied a double-sided reinforced retaining wall in a road project by using a centrifugal model test[9!. Displacements in a high double-sided retaining wall, the influence of different shapes of the retaining wall on displacements and the horizontal earth pressures acting on the retaining wall were studied. Zhu et al. studied displacements on the surface of the retaining wall, horizontal pressures acting on the reta
