Abstract
Municipal solid waste is a specific type of a soil-like material. Waste landfills are always placed near urban settlements and occupy sizeable territories, which are irretrievably withdrawn from circulation. As a result of the permanent process of waste generation, landfill areas are steadily growing. There has been a tendency of a landfill capacity increase in waste storage types of 20 and more meters in height lately. This height increment is accompanied by both the increase of loads applied to the subsoil and stresses and deformations in a waste massif. As a result, the evaluation of stability becomes necessary, for which physical-mechanical properties of waste, as well as prediction of their changes in time are required. The application of modern nondestructive methods of field determination of mechanical properties of waste has significant advantages over the traditional approaches. One of these nondestructive methods is a multichannel analysis of surface waves (MASW). This method allows measurements in the weathering zone of the near-surface part of the profile during the field testing of soils and soli-like materials, when it is practically unrealizable to select and restore undisturbed samples. When applying the MASW-method, the data along the geological cross-section are usually obtained as mean values along the defined depth, which is suitable for the investigations of homogeneous massifs of municipal solid waste.
