Geotechnical engineering labs are very important for civil engineers. It is well equipped with different equipment that help in evaluating different properties of a variety of rocks, chemical properties of soils, index properties, moisture content, rate of compression, consolidation, shear strength and other hydraulic characteristics of these materials. Geotechnical laboratories are very important for several civil engineers. Given below is everything you need to know about their services and how they help. What is geotechnical testing
Geotechnical testing involves finding out the conditions of soil, rock and other material that is used in construction and infrastructure development projects. These help in quality control and check the nature and extent to which different development projects can be carried out in an area. Geotechnical tests help in determining the topographic characteristics and the ground conditions of these places will support the same. It is involved in an investigation program where samples are collected and then laboratory testing is carried out where an investigation report is given. This report gives complete details about the inside ground condition and how different conditions will play a role in the developmental projects.
Geotechnical testing of soil
Geotechnical soil testing works for collection of soil samples by borehole determination and penetration. There are several different methods of soil sampling and investigation.
● Standard penetration and evaluation test is mostly done and it helps in finding out different densities formation parameters.
●The field vane shear test is done using a rod and the radial vanes are inserted in which soil. The rod is rotated as it helps in finding out the strength of the soil and presence of organic and inorganic materials in the same. It is also used to measure the drainage properties of soil.
●The cone penetration test is very helpful in site evaluation and characterization.
●It helps in finding out everything about the soil's liquefiable characteristics and the constituents. They also determine the variation in soil types, water pressure for hydrostatic levels, load bearing capacity and foundation bearing capacity.
Importance of geotechnical testing
Geotechnical lab testing is important for several reasons.
● It gives complete information about different properties of the soil and rock. ●It presents evaluated data about the moisture content of the soil, density, specific gravity and the different particle distribution in a particular soil. ● It also presents different compression strengths and shows if the project being carried out will be able to carry the load.
Geotechnical laboratory tests give a complete soil profile the deformation properties and strength parameters. These all are essential parameters that must be considered before any architecture of construction project is carried out. It helps in quality control and determines the future by giving an idea about the present condition of a site with proper analysis.
