Dams are generally classified according to its use, hydraulic design, construction design and material used in it. It is an inevitable necessity and a responsibility at the same time to evaluate the geological structure of the ground, the geotechnical properties and the geological environmental conditions. There are two different methods of truck drilling to achieve boring: truck-mounted boring with split spoon sampling and truck-mounted rock-core borings. This The design of a tunnel is determined in part by its use, length and depth, soil and geological conditions, topography and the structures that surround it.
