A soil sample recovered from a test boring using a split spoon sampler. Borings come in two main varieties: large diameter and small diameter. Large-diameter borings are rarely used because of safety concerns and expense but are sometimes used to allow a geologist or an engineer to visually and manually examine the soil and rock stratigraphy in-situ.
The standard penetration test (SPT) is an in-situ dynamic penetration test designed to provide information on the geotechnical engineering properties of soil. This test is the most frequently used subsurface exploration drilling test performed worldwide. The test procedure is described in ISO 22476-3, ASTM D1586 [1] and Australian Standards AS ...
In geotechnical engineering, a soil test can be used to determine the physical characteristics of a soil, such as its water content, void ratio or bulk density. Soil testing can also provide information related to the shear strength, rate of consolidation and permeability of the soil. The following is a non-exhaustive list of engineering soil ...
Symbol used in drawings. Simplified version of a cone penetrometer. The cone penetration or cone penetrometer test (CPT) is a method used to determine the geotechnical engineering properties of soils and delineating soil stratigraphy. It was initially developed in the 1950s at the Dutch Laboratory for Soil Mechanics in Delft to investigate soft ...
BS 5930. BS 5930:2015, "the code of practice for site investigations", is a UK code of practice which came into effect on 31 July 2015 British Standards Institution. It supersedes BS5930:1999+A2:2010, which itself supersedes BS 5930:1981 which in turn supersedes CP2001: 1957 "Site investigations". The stated purpose of the document is to ...
The National Cooperative Soil Survey Program (NCSS) in the United States is a nationwide partnership of federal, regional, state, and local agencies and institutions. This partnership works together to cooperatively investigate, inventory, document, classify, and interpret soils and to disseminate, publish, and promote the use of information about the soils of the United States and its trust ...
Base-cation saturation ratio (BCSR) is a method of interpreting soil test results that is widely used in sustainable agriculture, supported by the National Sustainable Agriculture Information Service (ATTRA) [1] and claimed to be successfully in use on over a million acres (4,000 km 2) of farmland worldwide. The traditional method, as used by ...
Soil surveys apply the principles of soil science and draw heavily from geomorphology, theories of soil formation, physical geography, and analysis of vegetation and land use patterns. Primary data for the soil survey are acquired by field sampling and by remote sensing. Remote sensing principally uses aerial photography, but LiDAR and other ...
