Dinding Penahan Tanah merupakan struktur untuk menahan tekanan tanah lagteral yang terjadi akibat perbedaan elevasi permukaan tanah dan juga beban luar. Beban yang akan dipikul dinding penahan tanah selain tanah timbunan juga beban kendaraan yang bekerja diatas tanah timbunan. Penelitian ini bertujuan untuk mngetahui besarnya tekanan tanah lateral yang terjadi akibat beban yang bekerja pada dinding penahan tanah dan juga stabilitas dinding pada proyek jalan tol JORR II ruas Kunciran – Parigi. Penelitian ini juga menghitung kebutuhan tulangan dinding penahan tanah. Perhitungan tekanan tanah lateral menggunakan teori rankine. Perhitungan stabilitas dinding penahan berdasarkan persamaan Hansen. Perhitungan penulangan dinding berdasarkan SNI Beton 2013 mengenai Tata Cara Perhitungan Struktur Beton untuk Gedung Khususnya BAB 14. Hasil Perhitungan Stabilitas dikatakan tidak aman terhadap gaya guling, geser, keruntuhan daya dukung yaitu masing – masing hasil sebesar 1,49< 1,5 ; 0,89

The retaining wall is a structure to withstand the lagged ground pressure that occurs due to differences in ground surface elevations and also external loads. The load that will be carried by the retaining wall other than landfill is also the burden of the vehicle that works on the landfill. This study aims to find out the amount of lateral soil pressure that occurs due to the load acting on the retaining wall and also the stability of the wall on the JORR II toll road project in the Kunciran - Parigi section. This study also calculates the need for reinforcement of retaining walls. Calculation of lateral soil pressure using rankine theory. Calculation of the stability of the retaining wall is based on the Hansen equation. Calculation of wall reinforcement based on SNI 2013 Concrete concerning Procedures for Calculation of Concrete Structures for Special Buildings CHAPTER 14. Stability Calculation Results are said to be unsafe against rolling force, shear, failure of carrying capacity, namely each yield of 1.49
