  1. Concrete 2001Perth September 2001 Barcoo Outlet Culvert The Influence of Soil-Structure Interaction on the Design of a Buried Arch Structure Doug Jenkins Interactive Design Services

  2. Focus: • Interaction of soil with deep raft foundations • Analysis methods for foundation design • Longitudinal effects on segmental culverts

  3. Culvert Design

  4. Culvert Design

  5. Cross-Section Analysis

  6. Raft Bending Moments

  7. Raft Bending MomentsEffect of Soil Stiffness

  8. Raft Bending MomentsFinite Element vs Beam on Elastic Foundations

  9. Raft Bending MomentsBending Moment vs Fill Height

  10. Raft Bending MomentsModulus of Subgrade Reaction vs Fill Height

  11. Longitudinal Effects3D Analysis

  12. Conclusions • Advantages of finite element analysis: • Soil properties based on standard tests • Model complex foundations • Model complete structure • Model construction sequence • Beam on elastic foundations • Simple and quick • But calibration against finite element analysis essential
