The shear size of bored piles refers to the diameter of the soil plug that is displaced during the drilling process. The shear size is an important factor to consider in the design and construction of bored piles, as it affects the capacity and integrity of the pile.

During the drilling process, the soil plug is displaced by the auger or drill bit, and the diameter of the soil plug is typically larger than the diameter of the auger or drill bit. The diameter of the soil plug depends on various factors, such as the type and strength of the soil, the diameter of the auger or drill bit, the drilling method, and the drilling parameters.

The shear size of bored piles can affect the bearing capacity of the pile, as it determines the area of the soil that is in direct contact with the pile. A larger shear size can result in a larger bearing capacity, as it provides a larger area of contact between the pile and the soil. However, a larger shear size can also increase the risk of soil instability and loss of soil support, which can compromise the integrity of the pile.

In the design and construction of bored piles, the shear size should be carefully considered and controlled, based on the specific requirements and conditions of the project. The shear size can be estimated using various methods, such as empirical correlations, laboratory tests, or field measurements. The estimated shear size should be used to determine the required diameter and length of the pile, as well as the required reinforcement and grouting.

Overall, the shear size of bored piles is an important factor to consider in the design and construction of deep foundations, and it requires careful attention to ensure the integrity and performance of the piles.
