Foundation of Bedrock
Mr. BigH the "design pressure" was 150KPa based on the Design load of the structure not the qa. The calculated Allowable Bearing Capacity (qa)based on Peck. et al graph is 2700 KPa..The area is located on a flat to undulating topography with slope ranging from 5-10 degrees. Can you suggest any...- akvargas

Type of Rock?
Mr. Fattdad and Ron the place is in Bukidnon, Philipines..The upper portion is consisting of a basalt bedrock..im sure it is a volcaninc rock with an igneous origin. the hardness is approximately 5MPA-50MPA.- akvargas

Foundation of Bedrock
Thanks fattdad for the reply.. The type of foundation is a mat foundation and the "exposed" bedrock covers all the proposed powerhouse with design bearing pressure of 150 KPa. I do have the Peck et. al. graph as a reference which gives the qa is per the RQD...but if you can provide another...- akvargas

Foundation of Bedrock
Can someone help me how to calculate the allowable bearing capacity of a bedrock of basalt? The bedrock is slightly fractured, slightly weathered and moderately strong (12.5-50MPa).I do appreciate if you can provide an excel spreadsheet...Thank you- akvargas
