Abstract: | Terowongan adalah suatu bangunan yang berada dibawah permukaan tanah ataupun pegunungan. 1.Bagaimana mengetahui lama waktu tunggu bebatuan akan mengalami keruntuhan dengan metode rock mass rating system (RMR) 2.Bagaimana menganalisa pengaruh kekuatan geser massa batuan terhadap standup time adapun metode yang digunakan pada penelitian ini menggunakan metode manual serta pada penentuan kekuatan geser massa batuan menggunakan metode 1.Dari hasil Analisa kekuatan massa batuan pada terowongan bendungan lau simeme menggunakan metode rock mass rating system (RMR) pada Sta 0+177 sebesar 55,5 dengan kelas batuan golongan ke III dengan waktu tunggu (Stand-up time) ±624 jam, Sta 0+327 sebesar 60 dengan kelas batuan golongan ke III dengan waktu tunggu (Stand-up time) ±840 jam, Sta 0+527 sebesar 71,5 dengan kelas batuan golongan ke II dengan waktu tunggu (Stand-up time) ±5040 jam, Sta 0+597 sebesar 58,5 dengan kelas batuan golongan ke III dengan waktu tunggu (Stand-up time) ±336 jam 2.Dari hasil kuat geser massa batuan kuat geser massa batuan terbesar yaitu pada sta 0+177 dengan nilai 22,84 Mpa dan kekuatan geser terkecil pada Sta 0+597 dengan nilai 10,017 Mpa 3.Berdasarkan nilai faktor keamanan pada setiap lokasi penelitian terowongan berdasarkan pada kriteria Mhor-coulumb, nilai faktor keamanan pada terowongan sebesar 1,0 sehingga masuk dalam kategori relative stabil 1. Tunnel is a building that is below ground level or mountains. 1. How to know the waiting time the rocks will experience collapse using the rock mass rating system (RMR) method 2. How to analyze the influence of the shear strength of the rock mass on the stand-up time as for the method used in this study using the manual method as well as on the determination of mass shear strength rocks using the Rock mass rating system (RMR) method. From the results of the strength analysis rock mass in the simeme lau dam tunnel using the rock mass rating method system (RMR) at Sta 0+177 of 55.5 with class III rock class with time wait (Stand-up time) ± 624 hours, Sta 0+327 of 60 with class III rock class with waiting time (Stand-up time) ± 840 hours, Sta 0+527 of 71.5 with rock class group II with a waiting time (Standup time) ±5040 hours, Sta 0+597 of 58.5 with class III rocks with a stand-up time of ±336 hours 2.From shear strength results of the rock mass shear strength of the largest rock mass shear is at sta 0+177 with value of 22.84 Mpa and the smallest shear strength at Sta 0+597 with a value of 10.017 Mpa 3. Based on the value of the safety factor at each research location based tunnel on the Mhor-Coulumb criteria, the value of the safety ] factor in the tunnel is 1.0 so included in the relatively stable category 1. |
