Obviously, the quality of undisturbed soil sample is considerably significant. This is because crucial engineering properties for foundation design, such as soil strength, permeability, and compressibility are estimated by testing undisturbed soil samples. There are several factors that influence the ...

Boring Methods for Soil Sampling for Soil Investigation
Boring methods are widely used for subsurface investigations to collect samples, in almost all types of soil, for visual inspection or laboratory testing. There are several boring techniques like auger boring, rotary drilling, wash boring, percussion drilling, auger drilling, and ...
Pressuremeter Test on Soil for In-Situ Stress Strain Determination
What is a Pressuremeter? A pressuremeter is a device which is used to determine the stress strain relations of in-situ soil by pumping it into the certain depth of borehole. It is designed by Menard of France so, it is ...
