How to Conduct Weight Sounding Test?
Weight sounding test is a form of penetration test conducted at construction sites to assess liquefaction susceptibility, soil profiling, determination of the bearing capacity of shallow and deep foundations, etc. The test consists of two stages, namely, static penetration and rotational penetration, ...
How to determine Depth and Number of Boreholes for Geostructures? [PDF]
The determination of adequate number and sufficient depth of boreholes is critical to gather enough data for the design and construction of geostructures such as foundations, bridges, retaining walls, cut slopes, and embankments. There is no specific rule to determine ...
What is Dynamic Cone Penetrometer(DCP)? [PDF]
Dynamic Cone Penetrometer, or DCP, is a tool used for evaluating the strength of soils on site. It also helps with monitoring the condition of granular layers and subgrade soils in pavement sections over time. It can be used to ...
Determination of In-situ Density of Soil by Water Replacement Method
The water replacement test method is used for the determination of field density of soil and rocks (includes materials that commonly contain particles larger than 75mm) in a test pit based on the ASTM D5030. It is specifically used for ...
Factor of Safety for Bearing Capacity of Soils
Factors of safety for bearing capacity is a value which is established based on the type of soil, method of exploration, level of uncertainty in soil, importance of structure and consequences of failure, and likelihood of design load occurrence. So, ...
What is Site Investigation or Soil Exploration? Objectives and Stages
Site investigation or Sub-Soil explorations are done for obtaining the information about subsurface conditions at the site proposed for construction. Soil exploration consists of determining the profile of the natural soil deposits at the site, taking the soil samples and ...
Underwater Soil Sampling- Equipment Types and Applicability
Underwater exploration is commonly required for the structures which are constructed in/under water. The foundations of the structures like bridge piers, pipelines, port structures, and oil well platforms have to be constructed with great caution considering every bit of information ...
