Liquid Limit Test of Soil by Casagrande's Method
Arthur Casagrande developed a standard device for the determination of liquid limit suggesting that at the water content of liquid limit a clay soil has a shear strength of approximately 2.5 kPa. The…

Advantages and Disadvantages of Standard Penetration Test
The Standard Penetration Test, also known as SPT, is an is-situ test of soil to evaluate the soil properties. Around the world, it is the most popular test of soil for subsurface exploration. The meas…
Boussinesq's Equation - Geotechnical Engineering
Boussinesq (1842 – 1929) evolved equations that can be used to determine stresses at any point P at a depth z as a result of a surface point load.
Boussinesq's F…
