What is anchored bulkhead? If tie rods or anchor rods are anchored close to the upper ends of sheet pile walls, the sheet pile walls are called bulkheads or anchored sheet pile walls. The tie or anchor rods are buried in the backfill at a considerable distance from the back of the wall. The ties or anchored rods reduce the lateral deflection, the bending moment and the depth of penetration. Anchored bulkhead are extensively used in water front Read more […]

## Cantilever Walls in Cohesive Soils

The pressure distribution on a cantilever wall constructed on cohesive soil is shown in Fig.1 below. The active pressure at any depth z can be expressed as: Pa = Ïƒv Ã— Ka – 2c√Ka Where, Ïƒv = Vertical pressure, Î³Z Z = Depth from surface to backfill The passive pressure at any depth y below the dredge line may be expressed as: Pp = Ïƒv Ã— Kp + 2c√Kp The active earth pressure on the wall from the backfill surface to the Read more […]

## Simplified Method of Structures of Cantilever Sheet Pile Walls

The exact method involves the solution of fourth order equation, which is quite laborious. For practical problems simplified method of structure of cantilever sheet pile walls is generally used. In the simplified method the passive pressure is replaced by concentrated load acting at the bottom of the pile. The simplified method arrangement is shown in Fig,1 above. Taking moments of all the forces about the base of the pile we get, ——— (1) Hence, KPD3 Read more […]

## Depth of Embedment of cantilever Walls in Sandy Soils

A cantilever sheet pile is shown in Fig.1 below. The Fig,1 also shows the pressure distribution. When the wall rotates about the point O’, the various pressures acting on the wall are: Pa1 = Active earth pressure on the back of the wall above the point O’ Pa2 = Active earth pressure in front of the wall below the point O’ Pp1 = Passive earth pressure in front of the wall above the point O’ up to dredge line Pp2 = Active earth pressure Read more […]

## Structures of Cantilever Sheet Pile Wall

Cantilever sheet piles are used where the height of the soil or water to be retained is smaller than 4.5 m. 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. General Principle of Design of Structures of Cantilever Read more […]

## Sheet Pile Walls | Types of Sheet Pile Walls

A sheet pile wall consists of a series of sheet piles driven side by side into the ground. This results in a continuous vertical wall for the purpose of retaining an earth bank. A sheet pile wall is a flexible wall having negligible weight and weight has no control over the wall stability. The stability is entirely due to the passive resistance developed between the wall and the soil. Sheet piles wall are generally used for water front structures, Read more […]
