Load parameters
 Seabed offset ΔsUniform distribution: 0 m∼8 m
 Intersection angle βUniform distribution: 5°∼90°
 Anchored cable length LaUniform distribution: 1 m∼2000 m

Soil parameters
 Effective friction angle ϕNormal distribution: μϕ = 35°, COVϕ = 0.09
 Effective unit weight γNormal distribution: μγ’ = 10.2 kN/m3, COVγ = 0.09
