Statistical Characterisation of the Geotechnical Properties of Bangkok Subsoil
https://orcid.org/0000-0001-8289-3647
Abstract Current geotechnical design requires an appropriate number of in-situ tests to obtain sufficient underground information. Subsoil properties are known to have high spatial variability and often fluctuate with location. Random field model considering soil spatial variability for reliability analysis in geotechnical engineering requires site statistical data. This study presents a statistical characterisation of subsoil properties in Bangkok. The boring log data of Bangkok subsoil was gathered and used to develop a 3D geological model. The statistical analysis of geotechnical data was performed to describe the spatial variability of soil properties. The mean, coefficient of variation, and scale of fluctuation of the undrained shear strength, standard penetration test, total unit weight, plasticity index, and thickness of soil layers were evaluated in detail using random field model. The lognormal distribution and decay exponential function were adopted to describe the fluctuation trend of soil properties. Based on the data, the empirical correlations between soil shear strength and index properties can be also established. The results of this research can help civil engineers to describe the influence of spatial variability of soil properties in geotechnical engineering analysis.
