Explain soil reinforcing techniques with its four necessities and strengthening of embankment. | Building Construction

Depending on the type of soil considered and the type of structure to be built, it is important to choose appropriate reinforcement techniques.  

Soil improvement techniques can increase the compactness of the existing soil, either by reducing the volume of voids, Soil reinforcement techniques themselves involve vertical or horizontal reinforcement elements in the soil. 

The objective of all these techniques is to allow the construction of a structure without excessive surface deformation or stability defects. 

In these techniques, they do not require excavation of the soil in place, thus reducing pollution related to the transport of materials and the risk of moving polluted soil.

Necessity of soil reinforcing techniques:- 

i) To build a high-speed line (HSL) in an area of compressible ground, when this is more economical than diverting the line. 

ii) To install warehouses in a port area in which the soils are often highly compressible due to coastal geology. 

iv) To build an airport on an artificial island in a marine environment.

v) To ensure the stability of the foundations, retaining walls, road embankments, railways etc.
