INTRODUCTION

Aziz Cross project is a signal free interchange with partial clover

leaf system and two additional directional ramps.

Clover leaf interchange Partial Clover leaf interchange with two

directional ramps instead of loops

INTRODUCTION

BASIC COMPONENTS OF FLYOVER

Bridge cross-section can be divided

into two portions.

1. Super StructureThis portion receives the live load

directly. For example, Box Girder

2. Sub StructureThis Portion supports the entire

structure and live loads. Piles Pile cap Piers Abutments

CONCRETE PILES

A pile is a vertical structural element of a deep foundation which transfers super structure loads to the earth farther down from the surface to a subsurface layer.

PILE CAP

PILE CAP

Pile cap is a thick

reinforced concrete mat that

rests on concrete piles that

have been casted into ground.

concrete pile cap distributes the

load of the superstructure (from

piers and abutments into the

piles.Pile Cap

PILE CAP AND PIER

PIER

A pier is a reinforced,

raised structure in form of

pillars typically supported by

well-spaced pile caps. It

transfers the loads from deck to

pile caps.

For this project, special shape

of pier is adopted. It as two

components

1. Pier Shaft as column

2. Pier Canopy as transom

Box Girder

Abutment refers to the substructure at the ends of a bridge span. It

supports; Super Structure load Live Load Lateral Earth Pressure

REINFORCED EARTH WORK

Reinforced earth wall is earth retaining structure and provided at

approaches (from road level to bridge level). The key components of a Reinforced Earth wall are geo-strips,

granular backfill and precast concrete facing panels. The frictional bond between the backfill supports the lateral earth

pressure and stresses induced due to traffic load.

PRE-STRESSED BOX GIRDERS

Bottom View of Box Girder

Piers

An optimal and most efficient design of beam is box girder. A box girder consists of enclosed tube with multiple walls.

The advantage of a box girder is that it better resists torsion. Having multiple vertical webs, it can also carry more load than an I-shape girder of equal height.
