of deepex on secant pile walls with our technical experts. in general the maximum excavation for a cantilever wall can reach up to 6m or 18ft. deeper cantilever walls have been constructed but these required more expensive wall systems such as t-type diaphragm walls. cantilever walls offer some advantages: advantages of cantilever walls:
sheet pile walls in which an increase in the height of the centre of passive pressure was attributed to the effects of wall bending. wall bending is just one possible factor causing a redistribution of the lateral stresses away from the linear-with-depth assump-tions that stem from the simple application of classical earth pressure theory.

a. sheet pile wall: a row of interlocking vertical pile segments driven to form an essentially straight wall whose plan dimension is sufficiently large that its behavior may be based on a typical unit usually 1 foot vertical slice. b. cantilever wall: a sheet pile wall which derives its support solely through interaction with the surround-ing soil.

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 straight forward but several modes of failure need to be considered. the most common problem with these walls is rotation about the
cantilever sheet piling walls depend on the passive resisting capacity of the soil below the depth of excavation to prevent overturning. the depth of sheet piling walls below the bottom of the excavation is determined by using the difference between the passive and active pressures acting on the wall.
cantilever concrete retaining walls are commonly used for residential purposes often as integral basement walls. usually the cantilever wall stem is of concrete block construction rising from an in-situ concrete foundation. the following worked example is for a free-standing cantilever wall that is considered
cantilever sheet piles cantilever sheet pile walls are usually recommended to use for walls of moderate height 6m measured above the dredge line. in such walls the sheet piles are act as a wide cantilever beam above the dredge line. the main step in analyzing cantilever sheet pile is to knowing the deflection
embedded retaining walls: theory practice and understanding sheet pile walls in which an increase in the height of the centre of passive pressure was attributed to the effects of wall bending. for example it may be seen that fp is reduced as h/h is increased.
this type of loading on sheet piles is especially important for hz walls and is demsonstrated in example 24. it is recommended that unless it can be shown that buckling of the piling is unlikely equation 2-4: mmax > paxial max ep 10. 2.2.4. section modulus of u- shaped sheeting
sheet pile structures depending on the way the retaining structure is built and analyzed it can be divided into three categories: 1. cantilever sheet pile 2. a few key points that define the lateral earth pressure in figure 8.7: 1. point a to point d p1 : active earth pressure on the right hand side.

sheet pile walls are generally used for the following: 1. water front structures for example in building wharfs quays and piers 2. building diversion dams such as cofferdams 3. river bank protection 4. retaining the sides of cuts made in earth sheet piles may be of timber reinforced concrete or steel.
9.3. cantilever walls. 9.3.1. overview. a cantilevered sheet pile wall performs somewhat like a cantilevered beam. the sheet piling is driven to a sufficient depth into the ground to become fixed as a vertical can- tilever resisting a load from active earth pressure.
structures of cantilever sheet pile wall. the various forces acting on a cantilever sheet pile wall are the active earth pressure on the back of the wall and the passive earth pressure on the front of the wall. the active pressure tends the wall to move away from the backfill while the passive earth pressure resists the wall movement.
this generally requires - the insertion of some type of wall support member below the existing ground and then excavation in front of the wall to the bottom of the exposed face. examples of this include soil nail soldier pile cantilever sheet pile and anchored sheet pile walls.

the sheet pile wall considered in this example is 0.5 m wide and has a height of 10.5 m. beam contact elements are used to create a frictional interface between the beam and solid elements that accounts for the full kinematics of the beam elements and allows the constant width of the wall to be represented in the model.
