Soil Dynamic Properties Assessment By Using Geophysical Methods

Soil dynamic properties are the most critical geotechnical property of soils, help in the stability of structures on or below the earth. The information on soil properties can be used in the preliminary design of the foundation. Conventionally, the geotechnical method is used in assessing the dynami...
