Evaluating the Undrained Shear Strength of Kalimati Soil Using Field Vane and Unconfined Compression Test; a Study on Applicability of Bjerrum’s Correction Factor

Rapid urbanization and geological challenges in Kathmandu have made it crucial to understand the geotechnical properties of soil region. This study here focuses on undrained shear strength silty clay Kalimati, Kathmandu, investigates applicability Vane Shear tests its parameters over other from methods. Geotechnical investigations were carried out at three locations within Engineering College premises in-situ laboratory conducted undisturbed disturbed samples. Then compared field vane strength, unconfined compression tests, For test correction factor as suggested by Bjerrum was used results indicate that this method overestimates Kalimati soil, indicating no adjustment is necessary. The findings important implications for design construction structures region, contribute a better understanding soil.
