Abstract :
Establishing the general nature of the strata below the ground and determination of the engineering properties of soil deposits and rock formations are the general objective of subsurface investigations. During site investigations, geotechnical borehole is one of the most commonly used Methods. Failure to conduct an appropriately scoped investigation can cause significant delays in the project and can potentially lead to either an over conservative and costly design or unsafe design. This paper provides guidelines for selecting optimum boring layout for various geotechnical features such as cuts, embankments, landslides, retaining walls, foundations and dams. The considering layouts were the boring depths, frequency and spacing. The findings have shown that the frequency and location of borings will depend on the anticipated variation in subsurface conditions and the phase of the investigation being performed, Whereas the depth of boreholes mainly affected by the nature of subsurface conditions. In this study, in order to optimize the geotechnical boring layout, the available criteria were discussed and depending on the subsurface conditions, some practical guidelines were presented.
