In-situ Soil testing Methods | Applications

Standard penetration test

In-situ Soil testing  In-situ soil testing is necessary to obtain the soil property information, to measure groundwater pressure, to gather the moisture content and other important data points. In-situ soil testing can be accomplished in a variety of different ways. Every soil test has its own place and benefit. Following are the in-situ tests which … Read more

Determinate and Indeterminate structures

Determinate and Indeterminate structures A structure is an arrangement of a number of components like slabs, beams, columns, walls, foundations and many others, which are in equilibrium. For this structure to exist, it has to satisfy the fundamental criteria of strength, stiffness, economy, durability and compatibility. It is generally classified into two categories for analysis, … Read more

Machine foundations and their vibration analysis

Machine foundations

Machine foundations and their vibration analysis Analysis and the design of the machine foundations involves careful evaluation of the vibration characteristics of the foundation system. This type of foundation undergoes dynamic loads which develop the vibratory motions which are taken by the soil below the foundation. This effect caused by the vibratory motions on the soil … Read more

Shrinkage Cracking in Concrete Structures | Long Term Effects

Shrinkage crack

Long-term Shrinkage Cracking of Concrete Internal or external restraints in a concrete structural element may resist free shrinkage of concrete, over time this leads to Shrinkage Cracking. In concrete structures, the volumetric reduction that happen due to the loss of moisture by evaporation is known as the shrinkage of concrete. This deformation is time dependent … Read more

Soil Nailing | Principles | Advantages

Soil-nailing-done-to-protect-the-highway

Soil Nailing Soil nailing is a ground improvement technique which is used to reinforce soil to make it more stable. Soil nailing is used for slopes, excavations, retaining walls etc. to make it more stable. The faces of steep slopes are usually protected by shotcrete and mesh for temporary works and by either cast-in-place concrete … Read more

Reinforced Soil | Principles of Soil Reinforcing | Advantages

soil reinforcement

Reinforced soil is the combination of compacted earth fill with tensile reinforcement to create an earth structure. The properties and performance of this earth structure depend on the bonding between the soil and reinforcement. The layout of reinforcement is done between the layers of compacted earth fill, which is an essential part of the construction … Read more

Factors affecting Compaction of Soil

Placing of soil over the reinforcement material

Factors affecting Compaction of soil Compaction of the soil is the process where the dry density of soil is increased by reducing air content or air voids present in the soil. This process is an essential part of the construction of any structure, as it strengthens the soil. Many factors influence the degree with which … Read more
