TO EVALUATE THE HYDRAULIC CONDUCTIVITY COEFFICIENT OF NON-COHESIVE SOIL IN GEOLOGICAL CONDITIONS OF SOME AREA IN HOCHIMINH CITY

Abstract

Researching underground hydraulic flow is very important for evaluating the water flowing volume quantity in many different hydraulic conditions, e.g. calculating water volume transference; pollution transference; consolidation problems. One of the main physical characteristics of soil that is used in those problems is hydraulic conductivity. In this paper, the author wants to make a comparison value of hydraulic conductivity is also call the permeability coefficient which got from indoor experiences and semi-experience equations by some of the foreign Authors. After that, the author means to suggest which equations can be used for the prediction the hydraulic conductivity in the simulation of underground flow.
