Retaining Wall Design Calculator

Retaining wall cost varies by material.

Retaining wall design calculator.

But if the wall deflects slightly stresses. Under normal conditions the lateral earth pressure is at rest condition. When retaining wall is designed for impact loads the stem should be checked at equally spaced points along stem length from top to the bottom as impact load spread at the greater length of the stem. The design of a retaining wall must account for all applied loads.

Based on our example in figure a 1 we have the forces due to soil pressure due to water and surcharge load to consider. Retaining walls can be built using a multitude of materials but they re most commonly built using wall blocks or timbers. Check the sliding resistance for a retaining wall. To estimate retaining wall materials using the calculator simply enter the wall length and width and the preferred block dimensions.

In the temporary condition no water will be taken into account. Calculate the lateral earth force acting on a retaining wall using the rankine formula. Retaining walls example 3 16 design of a cantilever retaining wall bs 8 110 the cantilever retaining wall shown below is backþlled with granular material having a unit weight of 19 knm 3 and an internal angle of friction of 30. Poured concrete is typically the most expensive followed by wood timber and then stones and pavers.

Check the resistance to sliding the turnover stability the bearing capacity and calculate the required areas of steel reinforcement for a proposed retaining wall. Design retaining wall for car bumper might be necessary when the wall extends above grade and the parking area is close to it. Assuming that the allowable bearing pressure of the soil is 120 knm 2 the. The loads that are of primary concern are the lateral earth pressures induced by the retained soil.

Retaining wall design for the professional practitioner and civil engineering student could not be found. Hopefully it will ease your comfort level when designing retaining walls and. There are a variety of materials you can use to build a retaining wall including patio stones wood and poured concrete. Retaining walls instantly enhance any landscape design.

A retaining wall refers to a structure that is designed and built up to defend the lateral pressure of soil when any alteration occurs in ground. Hence this attempt to condense simplify and compile information from many sources including my own experience into this book. Download the excel based calculation sheets for creating the perfect design of any retaining walls as well as verifying the suitability of this retaining wall against overturning and sliding forces.
