How Many Ways Are There To Do Geotechnical Testing? Geotechnical tests are carried out by proficient engineers or technicians. They perform these tests to understand the characteristics like physical properties that exist beneath a work site with the help of geotechnical testing equipment or equipments. In this article, we will talk about four major geotechnical testing types that geotechnical engineer performs. 1. 2. 3. 4.
Test pits Trenching Boring In-situ testing
Test pits As you expect, in this testing method, geologists dug a pit either manually or with an excavator to determine the sub-surface conditions to the depth desired.
Trenching Trenching test method is similar to test pits. The only difference is that the pit is elongated over some distance to find the reasons behind the change in sub-surface conditions over various parts of the work site. Engineers may take a range of soil samples with the help of shovels, manual augers, split spoon samplers, Shelby tube samplers, and modified California samplers.
Boring Generally small-diameter borings provide potential to engineers to manually remove soil or rock samples in order to perform testing. Borings allow the experts to see the actual materials, but of the certain types of soils. Act of boring can affect the soil conditions and engineers may get the inaccurate sample that cannot reveal the real conditions to support buildings and structures.
