Line Load Surcharge Retaining Wall Sheet

This surcharge shall apply as a rectangular distribution to the full height of shoring. In figure 1 where a semi gravity wall is shown the live load surcharge is placed over any element of the ers for settlement and bearing analysis while the live load surcharge is placed behind all the elements of the ers for sliding and eccentricity analysis. Surcharge location is 0 feet from shoring retaining wall height of retaining wall shoring is 10 feet traffic surcharge 𝑞 𝛾 𝑃 𝐻𝑒𝑞 30 pcf given in this example x 3 5 ft from table 1 105 psf.

The wall could be a basement wall retaining wall earth support system such as sheet piling or soldier pile and lagging etc. It can be either dead loads for example sloping backfill above the wall height or live load which could result from the highway or parking lot paving or adjacent footing. The live load surcharge is positioned to produce the maximum design load.

The earth pressure is acting. Wall from earth pressure surcharge load water earthquake etc. Surcharge loads acting on retaining walls are additional vertical loads that used to the backfill soil above the top of the wall. The stiffness of these elements can be modeled as linear elastic springs or fully nonlinear springs.

Retaining wall design example with surcharge load. Prior to completing any retaining wall design it is first necessary to calculate the forces acting on the wall. Four types of surcharge loads can be specified. Retaining walls generally have little vertical load other than self weight and weight of any soil on a footing.

In this example even thought the surcharge load is the same relative to the size of the earth pressures it seems much less significant. Loads and forces acting on retaining wall and their calculations the next step is to enter the loads on the wall as defined above. Struts or braces may be specified at any height s of the wall. Additional surcharge loads may be specified in the back side of the wall.

Vertical line load behind wall l lb ft or n m height of retaining wall h ft or m horizontal distance from wall to line load d ft or m output. Area load point load line load and or strip load. In this example the surcharge from a 10kn m line load located just outside the area of influence could contribute and extra 113 to the load on the shoring frame. However this isnt the case if the retaining wall is.
