- •
The suction stress in unsaturated soil was estimated from the wetting process of SWCC test
- •
The volumetric water content or matric suction in the soil was monitored in the field
- •
The infinite-slope stability in natural terrain considering the suction stress in the unsaturated soil was evaluated by calculating the safety factor based on real monitoring data
