geotechnical considerations in bridge design

Geotechnical considerations in bridge design involve studying the soil and rock beneath the bridge to ensure stability and safety. Engineers assess soil strength, drainage, and potential shifts like settling or erosion. This information helps determine the right foundation type and depth, ensuring the structure can support its weight and withstand environmental forces. Proper geotechnical analysis prevents future issues like sinking or cracking, ultimately contributing to the bridge's longevity and reliability. Thus, understanding the ground conditions is crucial for building safe and durable bridges.
