Presentation 3

  1. 1. TESTING STRUCTURES
  2. 2. What do geotechnical engineers do? Geotechnical engineers test soil and get samples from the soil (core samples) so that when earthquakes come the skyscrapers won't fall and break.
  3. 3. HOW THE MODELS ARE SIMILAR AND DIFFERENT TO REAL LIFE? Similar The model represents how they build the skyscrapers and how they use the pier foundations. Different When we shook our models it looked like a earthquake but in real life hands don't just come out of no where and shake the earth.
  4. 4. MY RESULTS OF SOIL IN AN EARTHQUAKE 1.Topsoil was unstable during the earthquake 2.Sand was unstable and fell during the earthquake 3.Clay was unstable and fell during the earthquake 4.Bedrock was stable and did not fall during the earthquake
  5. 5. ADVANTAGES AND DISADVANTAGES OF BEDROCK Advantages The structure won't be damaged. It'll be stable in the bedrock and not shake a lot. Disadvantages It takes a long time to dig that deep It'll take a lot of money And it's going to be hard to repair
  6. 6. WHY DID THE PIER FOUNDATIONS HELP? The pier foundation help cause the skyscraper to be stable since it goes down deep in the layers. Also, they help the skyscrapers from falling and breaking into pieces everywhere.
  7. 7. WHAT LAYER I WOULD RECOMMEND I would recommend bedrock because even though it takes a long time to dig, the building will not fall down and break, so you wouldn't have to rebuild it all the time.
