Soil bearing capacity is the maximum load soil can support without excessive settlement or failure. It's critical for foundation design.
단계별 가이드
- 1Use Terzaghi's formula with soil strength parameters (c, φ)
- 2Account for depth, shape, and inclination factors
- 3Results show allowable bearing pressure

피해야 할 일반적인 실수
- ✕Using generic values without site investigation
- ✕Neglecting water table effects
자주 묻는 질문
What reduces bearing capacity?
High water table, soft clay, and shallow foundations all reduce capacity significantly.
How is bearing capacity measured?
Plate load tests, boring logs with SPT, or laboratory testing provide site-specific values.
