| dc.description.abstract | Development of Abutment A1 RAMP 2 on Overpass Sta 0 + 716,523 Junction Kartasura Solo-Kertosono Toll Road I Multi Years, Karanganyar, Central Java, is planned to use pile foundation diameter 60 cm with 24 poles in one pole group. Abutment A1 RAMP 2 on Overpass Sta 0 + 716,523 Junction Kartasura is built between residents' houses, so the use of pile foundation creates sound and vibration that can be dangerous in surrounding buildings.
Researchers want to plan the construction with a bored pile foundation. The bored pile foundation is used to withstand large structural loads with excess no vibration that can disturb the environment. The bored pile foundation is planned with 3 alternatives, namely diameter 40 cm, 60 cm, and 80 cm. The purpose of this research is to know how big capacity of foundation support, diameter, and number of pole when using bored pile foundation. Designing bored pile foundation on Abutment A1 RAMP 2 development on Overpass Sta 0 + 716,523 Junction Kartasura using static method based on SPT test result. Abutment Analysis A1 RAMP 2 structure on Overpass Sta. 0 + 716,523 Junction Kartasura is intended to obtain an axial force and moment force. The result of the analysis of the capacity of support group of Mayerhoff method of diameter 40 cm, 60 cm, and 80 cm, obtained result 13842,290 kN, 14246,380 kN, and 15520,246 kN bigger than value P = 13784,9 kN, and method of Reese & Wright diameter of 40 cm, 60 cm, and 80 cm, obtained respectively of 14099.468 kN, 14804.441 kN, and 15441.556 kN greater than the value of P = 13784.9 kN, so the foundation bored pile with a diameter 40 cm, 60 cm, and 80 cm are safely used in the development of Abutment A1 RAMP 2 on Overpass Sta 0 + 716,523 Junction Kartasura. With various alternatives, namely diameter 40 cm, 60 cm, and 80 cm, taken the 3rd alternate diameter 80 cm Method of mayerhoff with the number of 14 poles in a group of poles. This is based on the number of poles that are used less, so it can save the time of work and construction costs incurred. In addition, the yield of the pile group support capacity (Qg) is greater than the axial load (P) and the total axial load (Pt) received, ie 15520,246 kN > 13784.9 kN and 15520,246 kN > 15441,449 kN , so that the burden of the building structure on the foundation can be retained by the pile foundation group. | id |
