DAMS-SLIP Documentation

📖 Overview

"Structural integrity is not negotiated with gravity — it is enforced through geometry, physics, and constraint design."

DAMS-SLIP (Dynamic AI-Augmented Monitoring System for Seepage, Limit-state Integrity, and Piping) is a fully coupled, AI-augmented continuum mechanics framework that treats structural integrity as a continuously governed dynamic invariant — not a static design property frozen at commissioning.

Contemporary earth-fill dam safety relies on static safety factors that cannot capture the progressive, spatially distributed, dynamically coupled nature of internal erosion and slope instability. DAMS-SLIP provides a principled three-construct governance pipeline that classifies any dam state in real time using AI-augmented predictions.

🏗️ 3-Construct + 3 AI Architecture

Construct 01 — SMEC (Seepage Mechanics and Continuity Engine)

Solves transient seepage in anisotropic, heterogeneous permeability field K(x,y,z) at N_mesh = 10⁶ elements. Tracks phreatic surface and monitors hydraulic gradient field in real time.

∂θ/∂t = ∇·[K(ψ)·∇(ψ + z)] + S(x,t)
SCI = |{x ∈ Ω : i_cr - i(x) ≥ 0}| / |Ω| × 100%

Construct 02 — GSSE (Geotechnical Slip Stability Evaluator)

Morgenstern-Price equilibrium solver over 10⁴ candidate surfaces + Sum-of-Squares polynomial global optimizer for certified F_s lower bound. Satisfies both force and moment equilibrium.

F_s* = min_{surface∈A} F_s(surface)
F_s,LB ≥ 1.45 (SOS-certified lower bound)

Construct 03 — HGCL (Hydraulic Gradient Consistency Lock)

Real-time exit gradient enforcement at downstream boundary. Activates Level 1 drainage, Level 2 drawdown recommendation, or Level 3 critical alert based on safety thresholds.

i_exit(x,t) ≤ i_cr(x) ∀ x ∈ ∂Ω_downstream
i_cr = (G_s - 1) / (1 + e) ≈ 1.03

AI Module 01 — CNN Gradient Detector

Convolutional neural network trained on 847 simulations + 23 historical piping incidents. Classifies gradient field into {normal, elevated, critical} at each time step.

Input: ∇h(x,y,t) 128×128 spatial grid
Output: P ∈ {0, 1, 2} · AUC = 0.97 · Precision = 0.94 · Recall = 0.91

AI Module 02 — PINN Pore Pressure Forecaster

Physics-Informed Neural Network embedding Biot consolidation equation as training constraint. Forecasts full spatial pore pressure field at T+6/12/24/48 hours.

L = λ_data·L_data + λ_phys·L_phys
λ_data=0.7, λ_phys=0.3, 24h MAE = 1.67 kPa

AI Module 03 — XGBoost Stability Ensemble

500-tree gradient boosting ensemble providing 24-hour F_s forecast with calibrated uncertainty. Reduces SOS solver computation time by 67%.

47-dim: PINN pore pressure percentiles, reservoir rate, current F_s, 12 principal components
F_s(T+24h) = μ ± σ · MAE = 0.024 · FAR = 3.8%
