文摘
- •
Foundation and overall structure designs of continuous spread footings are compared.
- •
Spatial variability of soil modulus is modeled by geostatistical methods using real data.
- •
Presence of geological anomaly increases settlement and bending moment estimations.
- •
Load redistribution effect reduces bending moment but it cannot completely absorb it.
- •
Overall structure design appears more appropriate approach in presence of geological anomaly.
