Soil Static Stiffness Please clarify whether the designer should consider the "soil type" based on the "N"values obtained (as per IS: 2911-Part-1/Sec-2, table-3, cl.

32 Vol-4, "Design Basis Report" (ED/Tech)



In all the shearing tests on sand it is not practicable to prepare undisturbed shear strength (triaxial/ direct shear) test samples. The soil samples are to be made approximately to the same density as it exists in-situ and tested either by direct shear or triaxial compression tests, it was meant that a sample of equivalent density has been prepared. Hence, it is requested that shear strength parameters for the tested samples should be considered in GIR.

The peak ground acceleration value (amax/g) as shown in Geotechnical Report for liquefaction potential analysis i.e. 0.24g is verymuch on higher side. Peak ground acceleration (amax/g) value of 0.143 was stated in the bulletin of the Seismological Society of America, Vol-92, No.2,pp-555-569,March 2002. Hence, the bidder proposes to consider Peak ground acceleration (amax/g) value as 0.143. Please confirm.
