Site Investigation, Drilling, and Sampling
Site investigation is the first step in solving most geotechnical engineering problems. The first part of this chapter deals with onshore site investigations, and the second part with offshore site investigations. A site investigation takes place in two steps: the preliminary investigation and the main investigation. Sometimes additional site investigation allows the geotechnical engineer to optimize the design and propose less expensive options. The preliminary site investigation takes place in two steps: a paper study and a site visit. The two most common methods of drilling for soil samples are the wet rotary method and the hollow stem auger. The objective in sampling a soil or rock deposit is to obtain samples that have the least amount of disturbance. The level of the groundwater at a site is a very important piece of information for any geotechnical investigation. Offshore investigations rely on geophysics in addition to geotechnical investigations.
