Abstract

The SAFER project had the aim of developing improved tools and enhanced datasets for seismic hazard assessment in Nepal. The project developed a geotechnical database for the Kathmandu valley (SAFER/GEO-591). During the project additional geotechnical site investigation data was collected including standard penetration testing and new borehole logging. Significantly, new Cone Penetration Testing (CPT) was carried out. This paper presents some further analysis of the collected CPT data and compares the test results against previously published analysis frameworks. The use of CPT data to estimate soil shear wave velocity in the Kathmandu valley along with normalisation procedures to account for the effects of stress level is discussed. Use of the new CPT data along with established soil classification charts is also presented in this paper.
