The electric cone penetration test (CPT) has been in use for over 40 years and is growing in popularity in North America. This paper provides some recent updates on the interpretation of some key geotechnical parameters in an effort to develop a more unified approach. Extensive use is made of the normalized soil behaviour type (SBTn) chart based on normalized cone resistance (Qt) and normalized...

To evaluate the effects of tillage and planting systems on soil physical properties, grain yied and its components, and milling recovery of rice (cv. Hashemi), an experiment was conducted at Rice Research Institute of Iran in 2017 and 2018 cropping seasons-using split plot arrangements in randomized complete block design with three replications. The experimental factors were; tillage methods (m...

Index properties such as the liquid limit and plastic limit are widely used to evaluate certain geotechnical parameters of fine-grained soils. Measurement of the liquid limit is a mechanical process, and the possibility of errors occurring during measurement is not significant. However, this is not the case for plastic limit testing, despite the fact that the current method of measurement is em...

Soil constitutes a fundamental resource for the production of food and fiber, thereby meeting diverse human needs sustaining global ecosystems. compaction electrical conductivity are key soil properties that can significantly impact health contribute to environmental challenges. The findings study shed light on severity compaction, with highest cone index 4495 kPa value recorded at depth 225 mm...

The evaluation of liquefaction potential of soil due to an earthquake is an important step in geosciences. This article examines the capability of Minimax Probability Machine (MPM) for the prediction of seismic liquefaction potential of soil based on the Cone Penetration Test (CPT) data. The dataset has been taken from Chi-Chi earthquake. MPM is developed based on the use of hyperplanes. It has...

SYNOPSIS Results of unconsolidated-undrained triaxial tests, field vane shear tests and cone penetration tests have been used to develop correlations between undrained shear strength and cone resistance for a soft to medium alluvial clay in the Lopez Canyon area of San Diego. When comparing uu triaxial results with cone resistance, the average cone factor was 11 with a standard deviation of 1.5...

Dynamic compaction is a soil improvement method which has been widely used for the increase of bearing capacity through stress wave propagation during heavy tamping. The cost and time of project implementation can be effectively curtailed by developing a model that can be used in the design of dynamic compaction operations. The numerical models offered so far are mostly one or two-dimensional, ...

 The present work shows the effects of different agricultural wheels traffic on soil physical properties a Typic Argiudoll worked under no-tillage cropping system. Soil compaction produced by was quantified through these parameters: a) cone index, b) rut depth and c) water content at moment. Grain chaser, sprayer, harvester combine tractor equipped with commonly used in study area were te...

The Yellow River Delta is located at the junction of and Bohai. impact function from river dynamics ocean tides make soil composition distribution in this area substantially complicated. In order to test variation layers Delta, were classified was calculated using cone penetration (CPT). following conclusions drawn: (1) measured mainly composed sensitive fine-grained soil, accounting for about ...
