Characterization of soil properties using various statistical approaches / Lim Jit Kheng, Ng Set Foong and Mohd Haris Ridzuan Ooi Abdullah
Soil is a complex engineering material by nature that formed by a combination of various geologic, environmental and physical-chemical processes. The inherent variability of soil and thus its uncertainty has been treated as a perpetual component in geotechnical design and construction that needs car...
