Earth pressure due to compaction
WebDec 21, 2024 · Thus, the compaction characteristics of crushed waste rocks (CWRs) are a key factor influencing the backfill effect of goaf [16,17]. If a certain lateral pressure is applied to CWRs backfilling goaf, the density and deformation resistance of CWRs can be improved . Additionally, the number of lateral loading cycles influences the compaction ... Webapplicable earth pressure coefficient, depends upon the degree of wall movement since movement controls the degree of shear strength mobilized in the surrounding soil. Calculating Lateral Earth Pressure Coefficients Lateral earth pressure is related to the vertical earth pressure by a coefficient termed the:

WebThe active earth pressure coefficient, K A, will be the same above and below the groundwater table, because φ and δ retain their values. Using the diagrams of Section 7.2, we get: φ = 30° δ =30° K A = 0.29. So the active earth pressure distribution on the wall will have the following form: The active earth pressures are: WebThe maximum lateral force, about the same as the design value, occurred during compaction of the backfill. Observations that differed from standard assumptions included the passive earth...
