| dc.description.abstract | Spatial variability influences the behaviour of foundation and therefore the performance of geotechnical structures. This research has carried out a quantitative analysis for site characterization and for prediction of soil engineering properties using statistics and geostatistical modelling techniques that are already used in geotechnical analyses but are rarely applied in the field of telecommunications. Site investigations have been carried out based on the procedures of telecommunication projects proponent in East Java province, Indonesia. The indicators of suitability for the East Java projects were the four elementary soil engineering properties namely plasticity index, void ratio, porosity and shear strength. The soil of East Java associated with the foundation of telecommunication projects were mainly high plasticity. The four indicators of suitability were used in the prediction and mapping. The spatial pattern of these indicators we used to identify the areas that have suitable characteristics for construction. Results from spatial autocorrelation have shown that the variogram modelling by REML estimator to be more acceptable for prediction and mapping in comparison to modelling without REML. This research produced prediction maps with a resolution of 1 km2 grids over 73 sites at eight different zones. The evaluation of site suitability mapping was carried out based on visibility, topography, land cover and soil properties, using the analytical hierarchy process (AHP) in order to determine the relative importance of all the selected factors. The result of site suitability assessment indicate that at Zone 2, Zone 3, Zone 4 and Zone 8 could be identified as suitable areas while Zone 1, Zone 5, Zone 6 and Zone 7 could be identified as unsuitable areas for development. Geostatistical modelling using the ordinary kriging has been successfully used to characterize soil engineering properties in each zone. This technique could be used as a diagnostic tool in order to identify the engineering properties of soils at site during the initial planning phase. The results indicate that this method could decide on the suitability a telecommunication site even with a smaller dataset. The procedures of this research could also be used to provide better guidance in prioritizing zones for site development. Furthermore, they offer a more reliable and informative approach that may be applied for in decision-making for the safe and economical land planning for the province of East Java. | en_US |
