Abstract

yang penting. Pada proyek relokasi gardu Induk PLN Indralaya, perhitungan perencanaan pondasi bukan hanya dipengaruhi oleh beban statis tapi juga beban dinamis yang ditimbulkan oleh getaran mesin yang sedang beroperasi. Jenis pondasi yang digunakan pada penelitian ini adalah pondasi rangka. Perhitungan daya dukung tanah dilakukan berdasarkan metode Terzaghi dan Mayerhof. Untuk analisis dinamis, dilakukan perencanaan dengan sistem trial error terhadap tiga tipe pondasi rencana. Keamanan pondasi terhadap beban dinamis diniliai dari faktor spring constcmt, damping ratio, magnification faetor, amplitudo dan velocity. Berdasarkan perhitungan, desain yang paling efektif adalah desain rencana pondasi rangka tipe 1 dengan dimensi slab (18m x 3,3m x 0,5m), dimensi kolom (0,3m x 0,3m x 4m), dan dimensi pile cap (18m x 3,3m x 0,75m). Untuk tiang pancang yang digunakan memiliki diameter 45cm dengan panjang 10 m. Pada tanah sedalam pondasi tertanam direncanakan penggantian material menjadi gravel dengan tujuan memperbesar modulus geser tanah. Kata kunci: Pondasi Mesin, Pondasi Rangka, Mesin Turbin, Generator
