1. We typically use load tests or pile driving formulas to test driven piles, because they are precast. List all the typical tests that are recommended on drilled shafts in order to ensure they are properly installed and ready to be integrated with the rest of the structure. 2. In case that a test drilled shaft fails, i.e. shows lower capacity than the one you have predicted in your design, what would you do?
1.
Drilled shafts, also known as drilled piers or bored piles, are deep foundation elements used in construction to support heavy vertical loads. They are typically used in areas with unstable soil conditions or where the loads are too great for shallow foundation systems like footings.
Drilled shafts are created by drilling a hole into the ground and then filling it with a structural material such as reinforced concrete. The size and shape of the shaft can vary depending on the requirements of the project, but they are typically circular in shape and range in diameter from a few inches to several feet.
Drilled shafts offer several advantages over other types of deep foundations. They can be designed to support very heavy loads, they can be constructed to great depths, and they are often less disruptive to the surrounding environment than other types of deep foundations. However, they can be more expensive than other foundation systems and the drilling process can be noisy and disruptive to nearby residents.
