GEOPHYSICAL TESTING OF MUNICIPAL WASTE LANDFILLS IN NORTHWESTERN CROATIA
Abstract
In the implementation of the characterization, i.e. the determination of the relevant mechanical and physical characteristics of the municipal waste landfill, it is necessary to define the optimal scope of the investigative works. The criterion of an optimum is determined by the minimum volume of planned actions with maximizing their performance. Generally, exploratory drillings give the so-called dotted data, with a regularly questionable quality of undisturbed and even disturbed samples. At the same time, they are economically disadvantageous given the usual unit cost of their implementation. Consequently, a number of relevant examples show that the application of geophysical methods is an optimal process for obtaining relevant information regarding the solution of various engineering tasks. For example, in determining physical-mechanical and geometrical properties of municipal waste a wide range of geophysical methods is used. The paper presents examples of geophysical methods for determining the necessary characteristics of municipal waste landfill in the northwestern part of Croatia. It has been shown that the volume and quality of the data obtained fully meet the requirements of the designer and the investor.
