Various ground improvement and soil stabilization techniques used in construction works are described.

Different Types of Soil Compaction Equipments -Types of Rollers

There are different types of rollers and other soil compaction equipments available. Use of these compacting machines depends on soil types and moisture conditions. Different Types of Soil Compaction Equipments: The soil compaction equipments can be divided into two groups: Light soil ...

Ground Improvement Techniques for Stabilization of Subgrade Soils

Stabilization of Subgrade Soils using Ground Improvement Techniques Essential prerequisite for High Speed corridor is to have control on the degradation of track geometry so as to keep various tolerances well within the specified limits. Degradation of track geometry is a function ...

Pressure Bulb or Stress Isobar Concept

Stress Isobar or Pressure Bulb Concept An isobar or pressure bulb is a stress contour or a line which connects all points below the ground surface at which the vertical pressure is the same. In fact, an isobar is a spatial curved ...

CONCEPT OF REINFORCED EARTH STRUCTURE DESIGN

Reinforced earth is a composite material formed by the friction between the earth and the reinforcement. By means of friction the soil transfers to the reinforcement the forces built up in the earth mass. The reinforcement thus develops tension and ...

Vibro-Stabilization Method of Ground Improvement

There are two methods of ground improvement or soil stabilization, i.e. by using surface rolling and by using vibro-stabilization methods. While surface rolling method is used for stabilizing or compacting soils on the top layer, vibro-stabilization method is used for compacting ...

Reinforced Earth Structures – Materials and Design Criteria

Reinforced Earth or Mechanically stabilized earth (MSE) is soil constructed with artificial reinforcing. It can be used for retaining walls, bridge abutments, dams, seawalls, and dikes. Although the basic principles of MSE has been used throughout history, MSE was developed in ...

How to Improve Soil Properties

Soil improvement in its broadest sense is the alteration of any property of a soil to improve its engineering performance such as strength, reduced compressibility, reduced permeability, or improved ground water condition. This may be either a temporary process to permit ...
