procedure for the design of retaining walls. a cantilever retaining wall. the first step is to obtain the value of ø and c by laboratory test. cohesionless backfill should used for a zone slightly larger than rankin zone if possible. select trial dimensions. this is to be able to get a solution for design. base maybe taken as 0.4-0.71 .
cantilever wall analysis example in deepex. a cantilever soldier pile wall example will be analyzed with deepex. the following data is available: a soil properties: sand, friction angle = 30 degrees, total unit weight 120 pcf, loading modulus of elasticity eload= 300 ksf, reloading modulus of elasticity eur = 900 ksf.
software such as mathcad or excel will be useful for design iterations. the example calculations are made here using mathcad. 1.2 example wall figure x.2. cantilever pole retaining wall example.
worked example: figure a.1-retaining wall cross section. consider the cantilever retaining wall with the cross section shown in the above figure a.1, which retain a 2m depth of soil having the groundwater table at -1.0m level.
purpose of calculation: the details of a cantilever retaining wall are shown below, is the design of the wall satisfactory? calculation reference: cr soil mechanics. r.f. cr calculation validation: check against a worked example in the reference above. calculation parameters : surcharge pressure thickness of the stem thickness of the base length of backfill height of wall from the base width of the base characteristics of backfill
software such as mathcad or excel will be useful for design iterations. the example calculations are made here using mathcad. 1.2 example wall . figure x.2. concrete cantilever wall example. the example wall is shown in figure x.2. the wall is assumed to be located in the christchurch port hills. the following design assumptions were made: soil type: port hills loess strength parameters: c = 0, = 30 degrees
example 11 - cast-in-place concrete cantilever retaining wall 7 2018 sliding check aashto per aashto , passive soil pressure shall be neglected. strength ia and extreme iia: maximum total horizontal force h = kip / ft. maximum total vertical force v = kip / ft. nominal passive resistance rep = kip / ft. aashto
various types of loads and forces acts on a retaining wall and their calculation is important for its design. these forces on retaining wall depends on various factors which are discussed. the main purpose of retaining wall construction is to retain soil that is why soil lateral earth pressure is

cantilever timber pole walls are probably the most commonly used form of retaining wall for residential purposes. the poles may also be of steel section for more heavily loaded walls. the design of these walls is relatively strht forward but several modes of failure need to be considered.
