On Jalan Pemuda DKI Jakarta, non level intersection will be designed which include flyover and underpass. Based on soil and environmental conditions around the site, a bored pile will be used to support the piers on the flyover, abutment, and piers on the underpass structure. Pile analysis includes bearing capacity and settlement. The bearing capacity of pile divided into two, namely axial and lateral bearing capacity. The axial bearing capacity of the pile is calculated manually, while the lateral capacity of the pile analyzed by LPILE. Pile group is analyzed by GROUP. Retaining wall designed on the left and right sides of the underpass use diaphragm wall. The diaphragm wall is disegned with 17 m depth and uses anchor support at 2 m and 5 m depth. The diaphragm wall using PLAXIS 2D with results deflection, internal forces, and stability. Reinforcement of pile and diaphragm wall are calculated manually and using SAFE. In this project too, an oprite embankment will be designed behind the abutment at both ends of the flyover. The oprite uses geotextile reinforcement to prevent the embankment from collapsing.
