Interpretation of CPTU Tests with Statistical and Geostatistical Methods

In the paper statistical methods for the interpretation of CPT data for the definition of subsoil stratigraphy have been applied to a subsoil CPTU data set of the Italian Center of Aerospatial Research (CIRA) in Capua (Italy). Results obtained by following the method proposed by Wickremesinghe and Campanella (1991) have been compared with those...

Automatic classification of fine-grained soils using CPT measurements and Artificial Neural Networks

Soil classification is a means of grouping soils into categories according to a shared set of properties or characteristics that will exhibit similar engineering behaviour under loading. Correctly classifying site conditions is an important, costly, and time-consuming process which needs to be carried out at every building site prior to the...

Remote prediction of soil types: A working methodology to predict Unified Soil Classification System (USCS) classes based on total geological history

The Dutch Ministry of Defence is interested in developing a tool or workflow that can be used to remotely predict Unified Soil Classification System (USCS) classes of any area to aid mobility-related decisions. Therefore, this study was initiated by Cohere Consultants in collaboration with NEO, a Dutch remote sensing company and Utrecht...

Comparative study of British and Malaysian peat soils pertainting to geotechnical characteristics

Peat soils occur in many countries and are described differently at times from both a qualitative and quantitative perspective. Peats are formed naturally through the decomposition of plant and animal matter under anaerobic conditions that take place over long periods of time. While the estimated and reported extent of Malaysian peat was...

Influence depth of lime application on organic soft clay

Soil-lime improvement is a common most effective me.fooimprove wet soft clay; many factors are involved in achieving the improvement. Mixing is one of those. The degree of pulverization plays an importance role in the efficiency of the improvement. The strength of treated soil depends on the lump size. A high degree of pulverization is expensive...

Geotechnical characteristics of peat

Peat soil is encountered in many areas and generally originates from plant/animal remains and is considered partly as decomposed biomass. Due to this composition, the structure of this soil is very different when compared with inorganic soils like clay, sand and gravel. Peat has a high compressibility, low shear strength, high moisture content...

Probabilistic classification of soils based on Local Average Subdivision method and CPT data

A random field generator based on Local Average Subdivision (LAS) method is proposed in this study in order to achieve probabilistic soil classification and quantify the uncertainty of the generated most probable geological cross section. CPT data and Robertson’s soil classification chart (1990) are adopted to classify the soil. The sole...
