DISCUSSION ON “IN-SITU” TESTS RESULT OF GEOTECHNICAL PARAMETERS As already mentioned, different in-situ tests including pressure meter and plate loading tests (as well as standard penetration tests) have been carried out to determine geotechnical parameters of the bed soil and geo-mechanical parameters of the bedrock mass in the spillway area, to find geotechnical parameter for slope stability analysis; following is a summary result of these tests. 1412
