| 英文摘要 | Soil arching has been recognized as a universal phenomenon in a number of earth structures, such as pile-supported embankments, twin tunnels, and anti-slide piles. Multiple soil arching exists in these earth structures, and stresses may progressively change with differential deformations during construction and service. However, the progressive development of multiple soil arching with deformations has not been well considered in current design. This paper reports a series of two-dimensional (2-D) trapdoor tests conducted with transparent soil to investigate the progressive development of multiple soil arching during trapdoor movement. The deformation and shear strain of the soil during the trapdoor movement were evaluated using the particle image velocimetry technique. The test results showed that soil arching on the multiple trapdoors was weakened by the interaction of adjacent trapdoors. The interaction effect decreased with the movement of the trapdoor. The normalized displacements above the trapdoor at maximum and ultimate arching states showed the slip surfaces at the inclination angles at 45 degrees + phi/2 and 90 degrees, respectively. Multiple soil arching was more mobilized within higher and denser backfill. Rapid movement of the trapdoor promoted the arching effect. This paper proposes a method for predicting the normalized trapdoor displacements at the maximum and ultimate states of multiple soil arching. |
