Principles of Retaining Wall Design - The Constructor

The basic pressure loading to be considered for the design is: Normal Loading = static earth pressure + water pressure + pressure due to live loads or surcharge. In general the resulting design pressure for earth retaining structures should not be less than the pressure due to a fluid of unit weight 5kN/m 3.【Get Price】

How loadings Applied to Retaining Wall

Machinery on Non Structural Slab Adjacent to or on Wall • Will increase soil lateral pressure to wall but less then machinery directly on soil due to slab’s pressure dissipating effect. Instead of 170 Ib/ft2 (two feet heavy soil’s EFP) we use 45 EFP as surcharge from machinery on non structural stab on 8 feet backfill. Non【Get Price】

Worked Example 2 | Design of concrete cantilever retaining.

Wall situation: Case 3: Retaining wall downslope and supporting dwelling foundations Surcharge: The surcharge from the dwelling was assumed to be 5 kN/m 2 averaged across the active soil wedge for the gravity case and 4 kN/m 2 for the earthquake case. Surcharge should be calculated using: ω = 1.2 G + 0.4 Q for the gravity case【Get Price】


2NOTES FOR EARTH RETAINING WALL DESIGN TO BS8002. EARTH PRESSURE ON WALLS. Soil Strength parameters. In BS8002 the design shear strength of the soil is based on the tangent of the friction angle reduced by a mobilisation factor M. For convenience design values of Φ' for M =1.2 are tabulated below.【Get Price】

Development of Traffic Surcharge Models for Highway.

Models have been developed to represent the horizontal load surcharges on abutment walls wing walls and other earth retaining structures due to traffic loads. These models have been developed based on an analysis of the global and local effects of the traffic loads in the UK National Annex to BS EN1991-2 and are different from the uniform pressure approach of BD37[1].【Get Price】
