Abstract
Helical pile is an alternative foundation with several advantages. It is easy and fast piling process, does not cause vibrations that could disrupt the soil in its environment and its bearing capacity is greater than the ordinary pile foundation. The bearing capacity of helical pile is contributed by the end bearing (Qb), shaft friction bearing (QS), and cylindrical bearing (QCyc) that is influenced by several factors such as diameter, configuration, and spacing between helis. This research was conducted experimentally in a laboratory using 2.1 m x 1 m x 0.95 m test box and sand as the medium. The diameter of pile was 1.5 cm, the length was 63 cm and the diameters of helical plates were 6 cm, 8 cm, and 10 cm. The spacing between helix of each pile were 20 cm, 15 cm, and 10 cm. The loading test was conducted using Quick Maintained Load (QML) Test while each of the test objects were analyzed using the Cylindrical Shear Failure Method because the value of S/D was ≤ 3. The result of this test were analyzed using Chin, Davisson and de Beer methods to obtain the ultimate bearing capacity. The results showed the percentage of difference between the test objects in terms of the influence of diameter on the space and this means for 10 cm, D06 to D08 48 %, D08 to D10 104 %; for 15 cm, D06 to D08 was 55% while D08 to D10 was 104%; and for 20 cm, D06 to D08 was 71% while D08 to D10 was 90%. Furthermore, Qb was found to be influenced by the diameter of the helix where it increases as the diameter helix increase. While QS and QCyc were influenced by the space between the helix, where they increase as the space between helix increases. The empirical calculations also showed Qb, QS, and QCyc contributed to the average ultimate bearing capacity by 59.4%, 2.1%, and 38.5%, respectively. It was concluded that the diameter provided the most significant effect to the bearing capacity of helical pile
