Abstract

Potential problems of rock-slope landslide were found in the construction of the new shortcut 4 road on the BTS national road section from Singaraja City to Mangwitani, Bali, Indonesia. The source of landslide potential is from andesite with intense stiffness found during excavation work of the road body. The potential for rock-slope landslides can threaten the bridge abutment building above. The andesite-slope product location of shallow intrusion is exactly on the shores of Lake Bratan. This study aims to determine the level of elevation of the slope based on each type of failure as well as empirical treatment recommendations. The research method was done by applying a local geological mapping to determine rock types, field measurements by scanning rock outcrop locations, and a calculation of rock-mass-quality values ​​using the Rock Mass Rating (RMR) method. Whereas the Rock Quality Assessment was carried out using the Rock Mass Rating (RMR) method, the slope evaluation was carried out using the Slope Mass Rating (SMR). The study used types of potential landslides and values, namely, planar landslides with an SMR value of 30.18 (Unstable) and a landslide probability of 0.6, wedge landslides with an SMR value of 57.6 (Partially Stable) and a landslide probability of 0.4, and the potential for tipping landslides with an SMR value of 47.6 (Partially Stable) and a landslide probability of 0.4. SMR values ​​indicate that rock slopes require further handling/treatment to get a stable slope. In addition, the slope angle of 650 is sufficient.

Abstract

Pembangunan jalan baru Bts. Kota Singaraja – Mengwitani (short cut 5-6) selesai pada bulan Desember Tahun 2019. Geometri jalan baru tersebut memiliki lereng buatan yang cukup tinggi. Beberapa lereng mencapai ketinggian 40 m dari permukaan jalan. Salah satu perkuatan pada lereng yang ada pada pembangunan jalan baru Bts. Kota Singaraja – Mengwitani adalah soil nailing. Kondisi saat ini lereng dengan perkuatan soil nailing dalam keadaan stabil. Namun perlu diperhatikan jika terdapat perubahan faktor lingkungan. Faktor tersebut adalah naiknya Peak Ground Acceleration (PGA) gempa. Variasi PGA dilakukan dengan nilai PGA 0,4g; 0.45g; 0,5g; dan 0,55g. Analisis deformasi dan stabilitas lereng menggunakan aplikasi Plaxis. Hasil analisis menunjukkan bahwa semakin meningkat nilai PGA maka deformasi pada puncak lereng semakin meningkat, sedangkan faktor keamanan semakin menurun. Peningkatan deformasi pada analisis ini memiliki hasil yang bervariasi dengan peningkatan beban gempa 0,05g, namun deformasi cenderung meningkat seiring dengan meningkatnya beban gempa. Untuk faktor keamanan, pada variasi beban gempa 0,4g;0,45g;0,5g terjadi penurunan rata-rata faktor kemanan sebesar 2,62%. Berdasarkan hasil analisis didapatkan prediksi saat lereng mengalami deformasi 0,09 m, faktor keamanan berada pada kondisi kritis (FK = 1). Deformasi ini dapat diukur dilapangan menggunakan inclinometer. Hal tersebut dapat digunakan untuk early warning sebelum lereng runtuh akibat gempa.
