As the setback of the wall increases, the size of the sliding wedge is reduced. This reduction lowers the pressure on the retaining wall. [4] The most important consideration in proper design and installation of retaining walls is to recognize and counteract the tendency of the retained material to move downslope due to gravity.
An embankment is a raised wall, bank or mound made of earth or stones, that are used to hold back water or carry a roadway. A road , railway line , or canal is normally raised onto an embankment made of compacted soil (typically clay or rock-based) to avoid a change in level required by the terrain , the alternatives being either to have an ...
Keyline design – Landscaping to optimize water usage; Land restoration – Process of restoring land to a different state; Grading (earthworks) – In civil engineering, creating a profile; Spoil tip – Pile built of accumulated spoil; Subgrade – Material underneath a road or track; Terrace (earthworks) – Terrain formed by tiered platforms
Highway engineering (also known as roadway engineering and street engineering) is a professional engineering discipline branching from the civil engineering subdiscipline of transportation engineering that involves the planning, design, construction, operation, and maintenance of roads, highways, streets, bridges, and tunnels to ensure safe and effective transportation of people and goods.
The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil. Reinforced walls utilize horizontal layers typically of geogrids. The reinforced soil mass, along with the facing ...
Return wing walls: used where banks are high and hard or firm. Their top width is 1.5 m and face is vertical and back battered 1 in 4. [ 2 ] Scour can be a problem for wing walls and abutments both, as the water in the stream erodes the supporting soil.
Jersey barriers on the road. A Jersey barrier, Jersey wall, or Jersey bump is a modular concrete or plastic barrier employed to separate lanes of traffic.It is designed to minimize vehicle damage in cases of incidental contact while still preventing vehicle crossovers resulting in a likely head-on collision.
Walls also can be used for lining channels and in cases of high flow, it is required that the outer cells contain concrete or cement slurry infill. CCS have been used to reinforce soft or uneven soil foundations for large area footings, for retaining wall strip footings, for load sharing of covers over pipelines and other geotechnical applications.
