Explanation:
Efficiency of pile group refers to the ratio of the actual load-carrying capacity of a pile group to the theoretical load-carrying capacity that would be expected if the piles were acting independently. The group efficiency can be influenced by several factors such as soil type, pile spacing, pile arrangement, and pile installation method.
Effect of Soil Type:
The group efficiency of pile group can be different for cohesive and cohesionless soils due to variation in soil behavior. In cohesive soils, the soil particles are tightly bonded, and the soil strength is governed by the cohesive forces. Therefore, the soil around the piles tends to move as a single unit, and the contribution of each pile is limited. As a result, the group efficiency of pile group in cohesive soils is less than 100%.
On the other hand, in cohesionless soils, the soil particles are not bonded, and the soil strength is mainly governed by the frictional forces. Therefore, the soil around the piles tends to move independently, and the contribution of each pile is significant. As a result, the group efficiency of pile group in cohesionless soils can be more than 100%.
Conclusion:
In summary, the group efficiency of pile group can be less than or more than 100%, depending on the soil type. The group efficiency will be less than 100% for pile group in cohesive soils and more than 100% for pile group in cohesionless soils.
