APPLYING KRIGING TO PREDICT THE DISTRIBUTION OF THE HOLOCENE SOFT SOIL STRATUM IN THE URBAN AREA OF HOCHIMINH CITY

Abstract

The Holocene soft soil layer in Hochiminh city is a special geotechnical unit to geologists and geotechnical engineers. Understanding the distribution of this special unit is very helpful for urban planners, investors, managers and geologists. Besides knowledge driven methods, data-driven methods, especially Kriging, are commonly used nowadays to determine the distribution of geological objects. However, Kriging is rarely used in the field of geotechnical engineering in Vietnam. This paper presents the map of thickness of soft soil layer which is interpolated by using Kriging for data of the urban area of Hochiminh city. In addition, this result is compared with one from existing maps and from direct measurements to evaluate the ability of applying Kriging in the field of geotechnical engineering.
