Case Study on Soil Settlement Problems in Urban Construction Projects in Ranchi, Jharkhand

Rapid urban construction in Ranchi, Jharkhand has increased cases of soil settlement in residential and commercial buildings. Many structures show cracks and differential settlement due to weak clayey soil, lateritic soil, and poorly compacted filled land. This case study investigates the causes of settlement problems in selected urban areas of Ranchi through field observations and review of soil investigation data. The study analyzes bearing capacity, consolidation behavior, and foundation types used in affected buildings. Results indicate that inadequate geotechnical investigation, improper compaction, and unsuitable foundation selection are major reasons for settlement. The study suggests proper soil testing, suitable foundation design, and ground improvement techniques to reduce future settlement issues in Ranchi.
