Design of Tegalluar High-Speed Railways Station is the project that consists of the main building with 2 floor and pedestrian tunnel which provide for accessibility of passenger from and to train-pelatform. This final project report aims to design the foundation that can support as well as transmit load from upper structure to soil and design the diaphragm wall that can retain from soil lateral force on the pedestrian tunnel project. Design of driven foundation consists of axial capacity and lateral capacity of a single pile. The foundation analyses about the negative skin friction effect caused by an embankment and soft soil layer in site. Design of single pile capacity will obtain pile configuration of which accommodate load-transfer from upperstructure. The driven pile foundation must be required on criteria design such as maximum deformation of nominal and strong earthquake condition, tolerable settlement and safety factor. Design of diaphragm wall is constructed to retain from soil lateral force on construction project. The excavation work is conducted till elevation of 6 meters. On this case, modelling stage will be execute with software PLAXIS2D that consists of wall and load penetration stage which represent real condition and 2 stage of excavation. Reinforcement design is determined from moment and shear force which come from PLAXIS2D modelling. Dewatering process is also worked for decreasing of ground water level in the vicinity of excavation. Diaphragm wall design is required in criteria design both maximum deflection as well as tolerable safety factor. This final project report will be finished on document, detailed drawing, and design specification.
