📋 Case Study

Mountain Resort RSRW for Road Realignment

Steep 45° natural slope with variable glacial till requiring rapid, low-impact construction

🏗️ Project Overview

Ski resort access road realignment, Colorado Rockies

🎯 Challenge

Steep 45° natural slope with variable glacial till requiring rapid, low-impact construction

🔧 Design Approach

📐 Key Calculations

Reinforcement Length (L)

L ≥ 0.7·H + (0.3·H·K_a·tanφ)

Result: 10.4 m

Ensured pullout safety factor > 1.5

Facing Connection Moment

M = w·s²/8

Result: 12.8 kN·m/m

Governed facing panel thickness selection

📊 Results

Built in 22 days during narrow summer window; zero post-construction settlement or face deflection

💡 Lessons Learned

• •Strip reinforcement orientation must follow principal stress direction
• •Facing panel joints require compressible filler to accommodate thermal expansion
