Pada perencanaan pembangunan Jalan Tol Pekanbaru ”“ Padang, terdapat rencana pembangunan terowongan, dimana dalam perencanaan terowongan diperlukan data kondisi geologi di permukaan dan bawah permukaan. Nilai kualitas massa batuan sebagai salah satu hasil penyelidikan geologi digunakan dalam desain metode penggalian terowongan dimana jenis batuan yang didapatkan dari daerah penelitian adalah batupasir kuarsa dengan sisipan batulanau yang memiliki tingkat pelapukan rendah hingga sangat tinggi. Analisis metode penggalian menggunakan ketentuan Pettifier dan Fookes (1994) dan Japan Society of Civil Engineers (JSCE, 2007), dimana dalam analisa tersebut diperlukan parameter parameter batuan dan tanah seperti nilai Rock Mass Rating (RMR) batuan permukaan dan bawah permukaan, pekerjaan laboratorium tanah dan batuan berupa indeks properties, petrografi batuan, dan point load test. Dari hasil analisis didapatkan metode penggalian yang tepat adalah Easy Ripping, Hard Ripping dan Very Hard Ripping dengan peralatan yang direkomendasikan adalah excavator dan road header. (Pettifer and Fokes, 1994). Tahapan penggalian terowongan mengacu kepada JSCE (2007) adalah kriteria C1, C2, D1 dan D2
Kata Kunci : penggalian terowongan, rock mass rating
