| Abstract: | Pergeseran tanah merupakan salah satu respons deformasi tanah akibat pembebanan. Fenomena ini terjadi ketika gaya luar yang bekerja pada tanah melebihi kapasitas geser internalnya, sehingga partikel tanah mengalami pergerakan relatif. Pergeseran tanah sangat penting dalam analisis stabilitas lereng, pondasi, dan struktur bawah tanah karena dapat menyebabkan penurunan daya dukung dan bahkan keruntuhan struktur. Penelititan ini bertujuan untuk mengetahui apa saja yang mempengaruhi nilai modulus geser tanah dan apa pengaruh nilai modulus geser tanah tersebut terhadap struktur bangunan. Penelitian ini dilakukan pada Proyek Pembangunan Pabrik Kertas di Tanjung Morawa dengan memanfaatkan data hasil penyelidikan tanah berupa nilai N-SPT. Untuk menganalisis modulus geser tanah ini penulis menentukan maksimum share modulus (Gmax) berdasarkan data bore log dengan menggunakan metode empiris Hardin dan Black. Berdasarkan hasil yang didapatkan untuk bore log 1 pada lapisan tanah pertama dipoeroleh Gmax =721,292 kN/m2 hingga lapisan akhir Gmax =15688,435 kN/m2 dan bore log 2 pada lapisan tanah pertama diperoleh Gmax =1606,555 kN/m2 hingga lapisan akhir diperoleh Gmax= 4471,735 kN/m2. Sehingga dapat disimpulkan semakin dalam lapisan tanah nilai gmax juga meningkat seiring kedalamannya. Nilai modulus geser yang tinggi menandakan bahwa tanah memiliki kemampuan yang lebih baik dalam menahan deformasi geser akibat beban yang diterima. Land displacement is one of the soil deformation responses due to loading. This phenomenon occurs when the external force acting on the soil exceeds its internal shear capacity, causing the soil particles to experience relative movement. Land displacement is very important in the analysis of slope stability, foundations, and underground structures because it can cause a decrease in bearing capacity and even structural collapse. This study aims to determine what influences the value of the soil shear modulus and what effect the value of the soil shear modulus has on building structures. This study was conducted on the Paper Mill Construction Project in Tanjung Morawa by utilizing soil investigation data in the form of NSPT values. To analyze the soil shear modulus, the author determined the maximum share modulus (Gmax) based on bore log data using the empirical method of Hardin and Black. Based on the results obtained for bore log 1 on the first soil layer, Gmax = 721.292 kN/m2 was obtained until the final layer Gmax = 15688.435 kN/m2 and bore log 2 on the first soil layer was obtained Gmax = 1606.555 kN/m2 until the final layer was obtained Gmax = 4471.735 kN/m2. So it can be concluded that the deeper the soil layer, the gmax value also increases with depth. A high shear modulus value indicates that the soil has a better ability to withstand shear deformation due to the load received.. |
