With the introduction of the concept of limit state was developed in parallel also the concept of characteristic value.
Eurocode 7 concerning the geotechnical design, introduces for the first time the characteristic values of geotechnical parameters.
The characteristic value, understood as a precautionary estimate of the parameter which influences the onset of the limit state into consideration, must be used in any type of geotechnical verification.
The works must be verified for the ultimate limit states that may occur as a consequence of different combinations of actions and for the serviceability limit state, defined in relation to the expected benefits.
The software calculates the characteristic values of the soil by analyzing the parameters obtained from the surveys. The geotechnical parameters are treated as random variables and the set of values of the parameters as statistical population; With CVSoil it is possible to import data from multiple surveys within the same area. Data entry is simple and intuitive; The area of investigation can be displayed on Google Maps. The parameters that can be statistically analyzed are: Angle of internal friction, Drained cohesion, Undrained cohesion, Relative density, Consistency index, Oedometric modulus of compressibility, Shear modulus, Young’s modulus, Nspt, Natural unit weight, Saturated unit weight, Pocket penetrometer, Poisson’s ratio, Uniaxial compressive strength, Static cone resistance, Natural moisture, Shear waves velocity, Custom parameters.
Normal Distribution Lognormal Distribution Student’s Distribution Bayes’ theorem small number of samples Calculation of geotechnical parameters according to the criterion of compensated and uncompensated resistance.
SHARING SURVEYS ON THE WEB
CVSoil is not a simple software for the determination of characteristic parameters, its architecture has been designed for the general organization of geotechnical tests. The users can choose to share their own surveys on the web. The publication will be done together with the details of the license owner, so the software will become a great advertising tool for the license owner. It is also possible to search for shared surveys with search filters based on area and distance from the place of investigation.
DATA EXCHANGE WITH OTHER GEOSTRU APPLICATIONS
CVsoil allows you to automatically import data from Static and Dynamic Probing. The processed data can be automatically sent to all GeoStru software. Output CVSoil creates a report that can be exported in the following formats: RTF, DOC, DOCX, PDF, HTM, JPEG etc.
