Liquefaction potential along the coastal regions of Karachi
Keywords:
Liquefaction potential; Coastal regions ofKarachi; Bore logs;Effective town-planning.Abstract
This paper investigates liquefaction resistance of the coastal belt ofKarachi stretched over 38 kms, the assessment is based on the scattered standard penetration test data of 120 bore logs.The liquefaction potential has been evaluated using simplified procedure developed by Seed and Idriss (1971) and modified by Youd et al. (2001). The results of analysis are transformed into maps, which are expected to serve as general guidelines for effective town-planning, designing efficient mitigation systems, ground-failure vulnerability and for future microzonation studies. This study endeavours to provide the basis on which a comprehensive microzonation map ofKarachi can be developed after some modifications.
