What are the different tests performed to identify the geological properties of the site?
The techniques de- scribed include penetration tests, shear strength tests, loading tests, pressuremeter tests and permeability tests as well as geophysical methods.
What is a preliminary geotechnical report?
A Preliminary Geotechnical Report (Soils Report) describes general topography and geology of a site location, including subsurface conditions, and provides initial information to be used by project architectural and structural consultants.
Which tests are usually performed in lab with soil samples collected during geotechnical investigation?
Index properties tests (moisture content tests, unit weight tests, specific gravity tests, atterberg limits tests, particle size distribution tests)
What are the methods of geotechnical investigation?
The geotechnical investigation and evaluation should include a balance of methods to acquire and evaluate subsurface information, including drilling and sampling, laboratory testing, geophysical surveys, cone penetration testing, and pressuremeter testing.
What are the 8 tests used to identify minerals?
Most minerals can be characterized and classified by their unique physical properties: hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.
What is the best possible soil for supporting a building?
Loam
Loam is the best soil type for construction due to its ideal combination of silt, sand, and clay. It combines the best of all their qualities into the ideal balance for supporting a foundation. Loam generally does not shift, expand, or shrink drastically and handles the presence of water very well.
What is sampling in geotechnical engineering?
Soil sampling Soil sampling is the process of collection of samples of soil in order to determine the engineering properties of soil required for the proper design of foundation Assessment of water table is also considered to be a part of soil exploration.
What are the different methods of site exploration in geotechnical engineering?
A geotechnical investigation will include surface exploration and subsurface exploration of a site. Sometimes, geophysical methods are used to obtain data about sites. Subsurface exploration usually involves soil sampling and laboratory tests of the soil samples retrieved.
Why is testing important in geotechnical engineering?
Consistent laboratory routines, suitable and well-maintained test equipment as well as proper interpretation of test results are essential to estimate the engineering characteristics of soil and rock materials to accurately predict their behavior.
