The purpose of geotechnical investigation is to research and characterize the geological conditions of the study area (including topographic, geomorphological conditions, geological structure, physico-mechanical properties of soil and rock, hydrogeological conditions…), then set up the reasonable technical and low-cost solution for the current project.
