How to Classify Soil Visually on site? Purpose: Visually classify the soils. Standard Reference: ASTM D 2488 – Standard Practice for Description and Identification of Soils (Visual –
Standard Penetration Test (SPT) Procedure Aim To perform standard penetration to obtain the penetration resistance (N-value) along the depth at a given site. Equipment & Apparatus Tripod (to
Values of Safe Bearing Capacity The safe bearing capacity of soil should be determined on the basis of soil test data or by performing some field test such
Laboratory Vane Shear Test of Soil Aim To determine shear strength of clay soil using laboratory vane shear apparatus. Theory In soil, shear strength is contributed by the
Boring Methods of Exploration The boring methods are used for exploration at greater depths where direct methods fail. These provide both disturbed as well as undisturbed samples
On-Site Identification & Classification of Soil The principle terms used by civil engineers to describe soils are Gravel (particle size larger than 4.75 mm) Sand (particle size within
Components Contributing Settlement of Soil Total settlement ρ in mm, which is the response of stress applied to the soil, may be calculated as the sum of three
Electrical Resistivity Test of Soil This method depends on differences in the electrical resistance of different soil (and rock) types. The flow of current through a soil is
Objective To perform plate load test to obtain a load-settlement curve of a soil at a particular depth so as to estimate the ultimate bearing capacity a foundation.
