Abstrak

Penelitian ini dilakukan untuk mengevaluasi pengaruh perbedaan profil sheet pile terhadap kestabilan tanah lempung menggunakan simulasi numerik berbasis PLAXIS 2D. Tiga jenis profil sheet pile dan tiga variasi kedalaman digunakan sebagai parameter bebas, dengan skenario perbandingan antara model yang menggunakan angkur dan yang tidak. Parameter yang diamati mencakup nilai faktor keamanan (safety factor) serta deformasi horizontal maksimum. Hasil simulasi menunjukkan bahwa seluruh kombinasi profil dan kedalaman menghasilkan faktor keamanan di atas batas minimum yang disyaratkan, yaitu 1,5. Penambahan angkur terbukti meningkatkan nilai faktor keamanan dan mengurangi deformasi, meskipun model tanpa angkur juga menunjukkan kestabilan yang memadai. Profil dengan kekakuan yang lebih tinggi cenderung memberikan performa yang lebih baik dalam menjaga stabilitas sistem.
