“…5, it can be seen that the soil type of all 11 canal-side roads at depth level 2 was the high plasticity clay, which is similar to the typical values reported by Kaufman and Hoekstra (2001). However, the electrical resistivity values of soil samples collected by many researchers were revealed in between < 1 and 12 Ωm (Giao et al 2004(Giao et al , 2008. The fluctuation of soil resistivity depends on their composition which in turn is influenced by region.…”

A resistivity-undrained shear strength equation was proposed in this work to investigate the relationship between the undrained shear strength and electrical resistivity of soft Bangkok clay. The field vane shear and screw driving sounding tests were used to evaluate the undrained shear strength of the soft Bangkok clay from 10 field investigations of the canal-side roads. Meanwhile, the electrical resistivity was collected by the low-cost nondestructive resistivity survey method. The relationship between the measured resistivity corresponding to the undrained shear strength was expressed as a linear equation of S u = 7.061ρ with a high statistical correlation (96.20%) between the undrained shear strength and resistivity. The validation between the predicted undrained shear strength from the equation and the measured undrained shear strength from the field sites confirmed the statistically significant relation of data and the reliability of the proposed equation. By using this equation, it successfully predicted the undrained shear strength of the soft Bangkok clay at a depth of 4.00-10.00 m below the ground surface of canal-side roads (zones C, D, and E in the zonation map). The proposed new equation from the resistivity survey in this work, therefore, serves as an alternative tool to fast estimate the shear strength of soft soil in the large area for the preliminary evaluation of road construction.

“…Finally, some authors combine as much information as possible from several geophysical and geotechnical methods to characterize an environment : Cosenza et al [2006] for example simultaneously use the dynamic penetrometer, the vane shear test, ERT, GPR and seismic refraction while Giao et al [2008] use drilling parameter recordings, cone penetrometer, field vane shear test, laboratory results and resistivity data.…”

‘Ethics’ is a branch of philosophy which examines the concepts of right and wrong. A journal will likely refuse to publish research, or writing, which they feel are not to an acceptable ethical standard. Ethics in science publishing refers to both the experiment and the written account. In terms of the experiment, publishers want to know that the researcher did not mistreat animals or human beings during the course of the study. Further to this, the writing is expected to be a truthful and honest account of the experiment. Finally, authors are expected to uphold a high standard of ethics by abstaining from any form of plagiarism. Interestingly, the United States National Academies begins their third edition of On Being a Scientist: A Guide to Responsible Conduct in Research with the statement, “The scientific enterprise is built on a foundation of trust” (2009). Not factual information, but trust that the information is indeed factual.
