Deep foundations transfer heavy structural loads to stable strata beneath weak surface soils. Under reamed piles are a specialized form of bored cast-in-situ piles featuring one or more enlarged bulbs near the…
Category: Geotechnical Engineering
The field geotechnical engineering deals with soil investigation and foundation design. The main purpose is to determine the bearing capacity of soil beneath our building or bridge or dam or any other construction.
Compaction of Soil vs Consolidation of Soil
Understanding the difference between soil compaction and consolidation is vital for any civil engineering project. Both processes affect soil strength, bearing capacity, and settlement behavior—but they operate on different time scales and…
Specific Yield and Specific Capacity of a Well
Wells are a significant source of groundwater for agricultural, industrial, and domestic use since evolution. The efficiency and sustainability of these wells depend significantly on their specific yield and specific capacity. Understanding…
What is Timbering? – Importance and Methods of Timbering
In the construction of foundations for buildings, timbering is used to prevent the collapse of side soil into the trenches. Trenches are excavated open space to facilitate foundation work. The main difference…
Foundation on Black Cotton Soil – Problems and Solutions
Black Cotton Soil exhibits considerable swelling and shrinkage with moisture content variation. This soil expands while soaked in water and shrinks in dry weather. This situation poses a problem for the foundation….
Geotechnical Investigation – Horizontal Directional Drilling
A geotechnical investigation is vital to determining the subsurface conditions of various construction projects, including horizontal directional drilling (HDD). An HDD method avoids the need for open-cut excavations by installing underground pipelines,…
Geotechnical Engineering Interview Questions
Here is a comprehensive list of interview questions in geotechnical engineering. Difficulties are varied from easy to professional level, so don’t be worried if you can not answer some of them. Geotechnical…
Most Useful Books for Geotechnical Engineering
There have been written thousands of books on geotechnical engineering that give extensive subject matter. Here is a list of the most useful books for geotechnical engineering that students and even faculties…
Types of Metamorphism – A Geological Phenomenon
Metamorphism is a part of the geological cycle or in other words rock cycle. Metamorphism changes the physical and chemical structure and properties of rocks. It could be classified as per the…
Types, Origin and Nature of Soil (in brief)
Unfortunately, soils are made by nature and not by man, and the products of nature are always complex… Transported soil: It is soil which is transported by means of natural agencies and…
Types of Pile Foundation (Explained in Detail)
Pile foundations are a type of deep foundation. They are adopted when firm ground strata are not available at shallow depths or the load coming from the superstructure is excessive. The way…
Types of Foundation for Building Construction and Their Applications
Foundation is often referred to as a substructure of a building. Foundations transfer the load coming from the superstructure safely to the beneath soil. Here, types of foundations and their use cases…
What is Soil Liquefaction? (Process, Causes, and Mitigation)
Soil liquefaction is a process in which, during an earthquake or application of dynamic load to the loose, saturated, and cohesionless soil, it loses its all shear strength under the action of…
Objectives and Requirements of Soil Classification System
Soil classification is the arrangement of soils into different groups such that soils in a particular group have similar engineering properties and similar behavior. It is a sort of labeling of soils…
