Abstract: In the installation of prefabricated reinforced concrete square pile practice, the driving criteria are usually primarily controlled by the tip elevation and the pile penetration rates are the secondary indices. In the practical engineering, due to the over emphasis of the total penetration length and the elevation, the pile heads are usually cracked and piles might be damaged. This project presents a penetration control formula based on the Hiley Approach. The WEAP analysis was performed and the results were satisfactory.
