Witryna27 cze 2024 · Like Prof Duncan frequently said, you can't analyze a wall as if the backfill soil was wished into place. For semi-rigid walls, how the backfill is compacted in place is a non-trivial factor on total lateral load. You could easily increase your lateral loads by 2X with moderate compaction effort in a narrow zone. Witryna18 lut 2024 · A new visual model was used to study the failure mechanism and earth pressure of cohesionless narrow backfill installed behind a rigid retaining wall. The …
Witryna22 kwi 2024 · The reason is that in the narrow backfill, with the large movement of the retaining wall to the soil, the backfill behind the wall will be squeezed, and the extrusion stress of the soil behind the wall, especially the soil with large buried depth, will also produce strain-softening behavior. Then the internal friction angle decreases, resulting ... WitrynaTake, and Valsangkar (2001) conducted centrifugal model tests on the narrow backfill width of an unyielded fascia retaining wall. Height of the model test was kept as 140 mm corresponding to 5 m high prototype wall, and backfill width was changed as 184, 75, 38 and 15 mm corresponding to aspect ratio in the range of 0.1 to 0.7.
