Feb 19, 2023 · In-situ testing refers to testing methods that are carried out directly on the ground, rock, or soil at a particular site. These tests are conducted to gather information about the geotechnical properties of the site, such as strength, stiffness, permeability, and deformation characteristics. In-situ testing is an important component of site investigation, as it allows engineers and geologists ...
- Nuclear Density Gauge. The nuclear density gauge or nuclear densometer is the industry standard for quickly and accurately determining the density, moisture content and air voids of a soil.
- Bearing Probe. A bearing probe or hand probe is a tool used by geotechnical engineers to roughly assess the bearing capacity of near surface soils. Bearing probes should not be the only tool used to assess soils on a site and should be used in conjunction with methods of investigation such as drilling, standard penetration tests (SPTs), and nuclear densometer testing.
- Vane Shear Test. The shear vane device is a metal rod with four thin metal blades welded orthogonally (at 90 degree angles to each other). After a borehole is drilled to the desired depth the vane shear device is pushed into the soil and rotated.
- Standard Penetration Test. The standard penetration test (commonly refered to as SPT) is the most popular investigative field test. During a geotechnical investigation wherein boreholes are being drilled, the SPT should be performed at regular intervals throughout the depth of every borehole.
Jul 24, 2022 · In-situ soil testing is necessary to obtain the soil property information, to measure groundwater pressure, to gather the moisture content and other important data points. In-situ soil testing can be accomplished in a variety of different ways.Every soil test has its own place and benefit.
66 C H A P T E R 5 In Situ Testing of Soil and Rock Introduction Because the vast body of natural soil and rock at the project construction site will serve as the primary bearing medium for new bridges, highways, cut slopes, walls, and embankments, in situ geotechnical tests provide valuable information concerning the field strength, deformation properties, stress state, and hydraulic ...
In-situ soil testing methods are performed directly in the field to assess soil properties and conditions at the site without the need for soil samples to be transported to a laboratory. These methods provide real-time data and are crucial for geotechnical engineering, construction, and environmental assessments.
Several in situ tests can be used to measure soil properties as they exist in place, without the need to extract soil samples from the ground and transport them to a laboratory for testing. There are many cases where this is preferable to collecting samples to be tested later in the laboratory, and in some instances, relative density for loose sands for example, may be the only economical way ...
