Applications of Numerical Modelling in Geotechnical Engineering

Posted on January 18, 2023March 16, 2023 By Civil Vedant
Applications of Numerical Modelling in Geotechnical Engineering

Numerical modeling in geotechnical engineering involves using mathematical equations and computer software to simulate and analyze the behavior of soil and rock. This is done by representing the soil or rock as a continuum, which is made up of a large number of small elements. Each element is defined by its own set of properties…

Compaction vs Consolidation

Posted on December 28, 2022December 21, 2022 By Civil Vedant
Compaction vs Consolidation

Compaction and Consolidation are two geotechnical processes that refer to the behavior of soil when it is subjected to pressure or load. These processes can have significant impacts on the stability and performance of foundations, slopes, and other structures that are built on or within soil. Understanding the differences between compaction and consolidation can be…

Standard Penetration Test

Posted on March 3, 2021March 3, 2021 By Civil Vedant
Standard Penetration Test

Standard Penetration Test (SPT) is an in-situ test, used to determine the relative density and angle of shearing resistance of cohesionless soils. This test is also used to determine Unconfined Compressive Strength (qu) of cohesive soils. The test employs a split-spoon sampler which consists of a driving shoe, a split-barrel of circular cross-section which is…

Triaxial Test – An Overview

Posted on March 1, 2021March 1, 2021 By Civil Vedant
Triaxial Test – An Overview

Triaxial test is used for determination of shear characteristics of all types of soil under different drainage conditions. In this test, a cylindrical specimen usually of length to diameter ratio of 2 (i.e. 76×38 mm and 50×100 mm) is stressed under conditions of axial symmetry. This test is carried out in two stages : 1st…

Index Properties of Soil (Basics)

Posted on August 9, 2020March 1, 2021 By Civil Vedant
Index Properties of Soil (Basics)

Index properties of soil are indicative of the engineering properties which are not of primary interest to the geotechnical engineer. From practical point of view, index properties of soil is a first come first serve property which needs to be find out to estimate the behaviour of soil i.e. before conducting major tests like compaction,…

Hazards related to Geotechnical Engineering due to earthquakes

Posted on August 3, 2020March 1, 2021 By Civil Vedant
Hazards related to Geotechnical Engineering due to earthquakes

An earthquake is defined as the sudden shaking of the earth surface caused by a source of disturbance inside the earth. Earthquakes occur due to sudden mass shifting in bedrock occuring along faults by the forces within earth. Such earthquales are called tectonic earthquakes. Earthquakes cause one of the most destructive natural disasters leading to…

What is Soil Investigation and how it is done?

Posted on August 1, 2020March 1, 2021 By Civil Vedant
What is Soil Investigation and how it is done?

Site investigation is a process of obtaining the information about subsurface conditions at a site where construction is proposed. It is generally done for big engineering projects. Information gathered from this investigation about subsurface is essential for design of structures and for planning construction techniques. Site Investigation basically consists of obtaining profile of natural soil,…

Foundation – Definition, Function and Types (Basics)

Posted on August 1, 2020March 1, 2021 By Civil Vedant
Foundation – Definition, Function and Types (Basics)

Foundation is a structure constructed to transmit load of superstructure to the underlying soil. The word “foundation” is derived from the latin word  fundare, meaning to set or ground on something solid. A foundation is a structure used to distribute loads of superstructure on large area. The foundation should be designed such that : 1….
