Narrow backfill meaning
Witryna30 sie 2024 · This study presents a new method to calculate the passive earth pressure on the rigid retaining wall of non-cohesive limited-width backfill. The proposed method considers the non-cohesive backfill behind the wall as the research object. It was assumed that under the translational mode of the retaining wall, the fracture surface … Witryna21 gru 2009 · Nobody knows exactly how erosion initiated, but one of the credible explanations is that the relatively narrow, vertical-sided trench in fissured volcanic bedrock allowed the fill to arch. This meant that the weight of overlying fill was carried by the trench walls, rather than as vertical stress in the core backfill.
