| dc.description.abstract | A weathered granite is distributed broad area in Korea. It is used base of support for a deep foundation in Korea. However, determining of material properties of the weathered granite is very difficult. Sample recovery of weathered granite is hard because it is easily broken and losing its rock structure during coring or drilling. Present research try to determine reasonable shear strength parameters, cohesion and internal friction angle of the weathered granite in Korea by field tests, pressuremeter test (PMT) and borehole shear test (BST). Moreover, present study try to assess applicability of these. Present study estimate shear strength parameters from PMT, BST, lab tests. The whole test results from PMT, BST, lab tests, and previous research are compared. Tests results performed in this study are not corresponded within themselves. Lab test results are considered as a true value for comparison of each results. | - |
