Laboratory Tests on Hydraulic Properties of Municipal Solid Waste

Abstract:

In order to analyze the hydraulic properties of municipal solid waste (MSW), laboratory tests on the soil-water characteristic curves of 6 groups of MSW samples with different void ratios and organic contents are performed by means of the unsaturated consolidation apparatus. The filter paper method is also employed to determine their soil-water characteristic curves. The distribution indexλof void size of the samples is analyzed. The results show that the air-entry value of the MSW samples is very small and about 1kPa, and it increases owing to the action of loading. The value ofλ decreases with the increase of the initial void ratio and increases with the increase of the organic content in the samples. For measuring the soil-water characteristic curves of MSW by means of the filter paper method, the values at high suction phase are more rational and significant.
