Fractal characteristics of soils at USM Campus

Fractal characteristics of soils at USM Campus / Ng Han Tiong
Serpihan ialah suatu geometri baru yang diberi perhatian dalam menjelaskan pelbagai jenis tanah asli. Pemahaman yang lebih jelas tentang ciri-ciri bahan dapat diperolehi daripada pembangunan dalam geometri serpihan. Suatu kes kajian untuk mendapatkan dimensi jisim serpihan untuk kawasan Kampus Kejuteraan, USM telah dibuat dan beberapa hubungan yang mengenainya telah dianalisis. Lima puluh sampel tanah telah dikumpul di merata tempat di Kampus Kejuruteraan, USM. Sampel tanah yang dikumpulkan ini telah dibahagikan kepada dua kumpulan, iaitu kumpulan sampel tanah untuk kawasan yang diganggu dan kumpulan sampel tanah untuk kawasan yang tidak diganggu. Taburan saiz zarah untuk sampel tanah ini dianalisis dan dimensi jisim serpihan untuk sampel tanah ini diperolehi. Dua hubungan mengenai dimensi jisim serpihan telah dianalisis, iaitu: (i) hubungan antara dimensi jisim serpihan dengan pelbagai ciri-ciri tanah dan (ii) hubungan antara dimensi jisim serpihan dengan kegangguan tanah. Empat ciri-ciri tanah yang telah digunakan dalam analisis ini adalah kandungan kelembapan, ketumpatan pukal, kandungan organik dan kandungan tanah liat. Keputusan untuk hubungan antara dimensi jisim serpihan dengan pelbagai ciri-ciri tanah adalah baik dan adalah sepadan dengan teori. Bagi analisis yang mengenai kegangguan tanah, dimensi jisim serpihan untuk kawasan yang tidak diganggu adalah lebih tinggi daripada dimensi jisim serpihan untuk kawasan yang diganggu. _______________________________________________________________________________________________________ Fractals are a concern new geometry to describe the variety of natural soil structures. Better understanding for the material properties can be obtained by the development in fractal geometry. A case study was carried out at the USM, Engineering Campus in Nibong Tebal, Malaysia to determine the mass fractal dimension in that area and some relationship that related to the mass fractal dimension was analyzed. Fifty soil samples were taken at various locations in USM, Engineering Campus. These soil samples were separated into two categories which are disturbed area soil samples and undisturbed area soil samples. The particle size distributions of these samples were analyzed and the mass fractal dimensions of these samples were determined. Two relationships which related to the mass fractal dimension were carried out, there were: (i) relationship between mass fractal dimension and the soil properties and (ii) relationship between mass fractal dimension and land disturbance. Four soil properties that use in the analysis were moisture content, bulk density, organic content and clay content. The results for the relationship between mass fractal dimension and soil properties were good and similar to the theory. From the analysis of the land disturbance, the mass fractal dimension for the undisturbed area was higher than the mass fractal dimension for the disturbed area.
