ABSTRACT
Kathmandu Valley, the capital of Nepal, is a highly populated and rapidly urbanised area of the country built upon lacustrine and fluvial origin deposits. Because the valley deposit is located in an earthquake-prone zone with a long history of catastrophic earthquakes, it is vulnerable to numerous geohazards like liquefaction. Although a few localized geotechnical studies have been conducted in the valley, holistic understanding, modelling, and geotechnical soil characterisation are seldom documented. This study attempts to characterize the Kathmandu soil based on geotechnical properties using statistical analysis approach. We have collected and analysed more than 400 geotechnical investigation reports and bored 10 test locations. Statistical analysis and representation of index properties, consolidation parameters, shear strength, SPT-N value, and shear wave velocity have been assessed in this paper. These findings can aid structural and foundation engineers in studying foundations, cost estimation of geotechnical investigations, and planning and implementing various civil engineering projects.
