Soil Disturbance Assessment in Soil Sampling of Open Tube Sampler and Rotary Core Drilling
Type Of : Academic Manuscript
Type : Science
Soil disturbance due to soil sampling is of outmost importance for researchers and geotechnical engineers. This research studied on the Belgian Boom clay comparing of soil sample disturbance for two soil sampling techniques. Firstly, an open-tube sampler is a common soil sampling method used in Belgium. The open-tube sampler applied the thin-walled tube for soil sampling quality class A. Secondly, the rotary core drilling with triple tube wire line coring sampling system is a new technique and operates faster than the first technique continuing to the greater the depth. However, its fast operation might cause soil sample disturbance. Therefore, the research studied on samples from two sampling techniques using index tests and triaxial tests with bender elements technique which is a new technique to assess the soil disturbance calculating the initial shear modulus, G0, from the elastic shear wave velocity. It is shown that the new sampling technique can obtain as high quality sample as the open-tube sampler.
