k_su: f64

Strength gradient with depth [Pa/m].

compression_index_cc: f64

Compression index Cc [-].

recompression_index_cr: f64

Recompression index Cr [-].

cv: f64

Coefficient of consolidation Cv [m^2/s].

e0: f64

Initial void ratio e0 [-].

gamma_sat: f64

Saturated unit weight γ_sat [kN/m^3].

Implementations

impl SeabedSedimentModel

pub fn new( su0: f64, k_su: f64, compression_index_cc: f64, recompression_index_cr: f64, cv: f64, e0: f64, gamma_sat: f64, ) -> Self

Create a new seabed sediment model.

pub fn gulf_of_mexico_clay() -> Self

Typical soft marine clay (Gulf of Mexico).

pub fn undrained_shear_strength(&self, depth_m: f64) -> f64

Undrained shear strength Su at depth z [m] [Pa].

Su(z) = su0 + k_su * z

pub fn settlement_primary( &self, sigma_v0: f64, sigma_vf: f64, h: f64, e0: f64, ) -> f64

Primary consolidation settlement ΔS [m].

ΔS = (Cc / (1 + e0)) * H * log10(σ_vf / σ_v0)

pub fn time_to_consolidation(&self, cv: f64, h_dr: f64, u: f64) -> f64

Time to reach a given degree of consolidation U (Terzaghi 1-D).

T_v = Cv * t / H_dr^2, solved for t: t = T_v * H_dr^2 / Cv

pub fn ocr(&self, sigma_v: f64, sigma_p: f64) -> f64

Overconsolidation ratio OCR at depth z given preconsolidation pressure.

pub fn pore_pressure_ratio(&self, u_excess: f64, sigma_v_eff: f64) -> f64

Pore pressure ratio ru = u / σ’v.
