Summary of uncertain parameters and their statistical characteristics.
| Parameters | Distribution |
| Load parameters | Seabed offset Δs | Uniform distribution: 0 m∼8 m | Intersection angle β | Uniform distribution: 5°∼90° | Anchored cable length La | Uniform distribution: 1 m∼2000 m |
| Soil parameters | Effective friction angle ϕ | Normal distribution: μϕ = 35°, COVϕ = 0.09 | Effective unit weight γ′ | Normal distribution: μγ’ = 10.2 kN/m3, COVγ’ = 0.09 | Cable burial depth H | Uniform distribution: 0.1 m∼1 m |
