Geotechnical analysis involves several steps. First, gather information about the project location, including soil types and site history. Then, conduct site investigations to collect soil samples using techniques like drilling or excavation. Perform laboratory tests on the soil samples to determine their physical and mechanical properties. Analyze the data to assess soil behavior, stability, and the potential for settlement or deformation. Finally, use sophisticated software or manual calculations to interpret the results and provide recommendations for foundation design, slope stability, or other geotechnical issues.«Geotechnical engineering handbook »
