- •
Stress–strain responses of buried pipeline under ground overload were investigated.
- •
Effects of overload, pipeline and surrounding soil parameters were discussed.
- •
No-pressure pipeline is more prone to failure than pressure pipeline.
- •
Stress and strain first decrease and then increase as internal pressure increases.
- •
A protective device of buried pipeline is designed for preventing ground overloads.
