A method commonly used to stabilize expansive soils is mixing the soil with foreign materials. The main obstacle raised from soil stabilization in the field is the difficulty in mixing process. This paper presents the strength distribution in soft soil due to the addition of single columns of quicklime and carbide waste- product from gas industry that contains Calcium Oxide (CaO) up to 60%. The results show that the addition of columns filled with carbide waste product and quicklime increase the shear strength of surrounding soil. The spreading of the strength tends to follow a unique pattern, that the increase of soil shear strength at a certain normalized-distance, S (in column diameter D) from the column axis is constant. A significant increase of strength occurs in the area closer to the column, and it decreases with the distance from the column.Abstract in Bahasa Indonesia :
Metode yang umum dipakai untuk menstabilisasi tanah adalah mencampur tanah asli dengan material lain. Kendala utama yang timbul pada stabilisasi tanah di lapangan adalah kesulitan pada proses pencampuran. Makalah ini mempresentasikan penyebaran kekuatan tanah akibat kolom tunggal yang terbuat masing-masing dari kapur aktif dan limbah karbit, yang mengandung unsur Calsium Oksida (CaO) sampai 60%. Hasil penelitian menunjukkan bahwa penambahan kolom limbah karbit dan kolom kapur dapat meningkatkan kekuatan tanah di sekitarnya. Penyebaran kekuatan tanah di sekitar kolom kapur dan limbah karbit cenderung mengikuti suatu pola yang unik, yaitu bahwa peningkatan kekuatan tanah pada jarak (yang dinormalisasikan dengan diameter kolom D) adalah tetap. Peningkatan kekuatan geser tanah yang signifikan terjadi di daerah dekat kolom dan peningkatan ini mengecil seiring dengan jarak dari kolom.
