Benefits Of Geotechnical Lab Testing and Types Of Geotechnical Tests

Geotechnical lab testing

Just like everything needs to be tested before using similarly soil also needs substantial amount of testing before either using it or making anything else to use it on. There are several projects which need soil to be tested such as agriculture, construction and even mines.

Agriculture

It is very important to test the quality of soil before it can be used for agriculture. Since agricultural produce is directly used for human and animal consumption therefore it is very important to check is the soil is fertile enough from ploughing and if it does not consist of any harmful substances such as poisonous chemicals which can harm the produce and then enter the human body. In order to check the properties of soil Geotechnical lab testing is conducted.

Construction

With more and more housing demands and industrialization, construction has become wide spread. With an increasing demand for infrastructure such as roads and building, it becomes important to build schools, hospitals and roads. But before construction can take place it is important to find out whether the soil is able enough to hold the pressure of this construction. How is this found? The intensity of the soil to hold in order to construct bridges, buildings power plants and highways etc. can be found out by several tests which involve geotechnical tests.

Mines

India is blessed with many expensive treasures such as coal mines, gold mines and even diamond mines. In order to find out where these important and expensive mines are located, it is important to conduct test and find out results ,There are complex equipment’s which are used to find out the reserves and then carry out mining which adds to the wealth of the nation.

Distinct Types Of Geotechnical Testing Used By Lab Experts

There are many laboratory which test various kind of soil from various offshore and onsite projects from various locations which are tested depending upon the future project. These laboratories not only conduct experiments domestically but also tale projects from all around the world. There are well trained staff which consist of geologist and engineers who are a part of this team and work round the clock to get the most accurate results.

There are various tests which are undertaken by many laboratories. Following are some of the test which are widely used

Static testing – triaxle stress path, direct simple shear, ring shear, unbroken rate of strain alliance

Dynamic testing – booming column, torsional shear, cyclic triaxial, cyclic direct modest shear, pulse speed

Extrusion and preparation of up to 6-inch diameter uninterrupted samples

  • Organization
  • Mechanical grain size and hydrometer examination
  • Water quality
  • Waterberg limits
  • Loose density tests
  • Q and R triaxial compression tests and relativity test
  • Penetrability tests including flexible wall permeameter tests
  • Compaction tests (15/25 blow)
  • Direct shear tests
  • Consolidation tests

Apart from these test there are several other test and many tests which are specific to requirements which are conducted in close supervision of engineers and are conducted with the help of state of the art technology and instruments.
