How to identify soil layers in pile foundations

We will make a pile foundation for the first time As we understand from the ground survey, there is a filling of up to -6.33, it is 3.93 cm from the bottom of the foundation. It was said to be 1.5 times piles, that is, 6 meters. I read the information on how to define the data, but I failed. How do we get the coefficient from the study?
 
Re: Pile Foundation Hello, We could not see any information other than the bedding coefficient in the content of the soil report you added. You can request the adhesion factor and the undrained slip resistance value from the person and institution that prepared the study. We understand from the ground report that the ground on which the building sits is approximately 4m of filling. If the ground fill and cohesion value is zero, ideCAD makes the pile calculation only for cohesive soils. So you can't calculate the frictional force on the piles in these cohesionless soil layers. After acquiring the necessary soil parameters, soil layers can be defined by considering the schematic figure in the ideCAD help document. In the pile foundation analysis, it is assumed that the piles carry the structure completely, and the bearing coefficient under the raft foundation is zeroed. Set the "Bearing coefficient" value to 0 in the Analysis settings / Foundation soil tab. If you analyze without zero, you will be warned. At this stage, you can change the bed coefficient value if you want. In your design, 6 piles are defined in the structure, these piles will be insufficient. If we call the pile diameter D; It would be appropriate to define piles with 2.5D - 3.5D intervals in X and Y directions. ( This is the optimum range suggested by Prof. Dr. Zekai Celep in a presentation. ) Another suggestion is to add an additional basement floor to the building by meeting with the owner of the building. In this way, it may be appropriate to build an additional floor instead of incurring the cost of piling by reaching the solid ground under the fill.
 
I think it would be a nice innovation if we could see the ground layers in 3 dimensions in the new versions.
