Geotechnical properties of municipal solid waste at different phases of biodegradation.

The Second International Conference on Soil Mechanics and Foundation Engineering is to be held in Rotterdam during June 21–30, 1948, on the invitation of the Netherlands Government and the Municipality of Rotterdam. The following subjects have been selected for discussion: (A) Technical and Scientific Topics: theories, hypotheses, considerations of general character; investigations in the laboratory and in the field; stability and deformation of earth and earth constructions; stability and movements of soil-retaining constructions; stress distributions under foundations and settlements of structures; pile foundations, pile loading tests; problems in highway and runway constructions (superstructure); methods for improving the mechanical quality of soils; ground-water movements. (B) Topics of a General Character: survey of the existing institutions and individuals working in the sphere of soil mechanics; suggestions for international co-operation. Anyone interested in the Conference, whether from the point of view of practical application, research or teaching, is welcome to attend the meetings and to contribute reports or discussions. The president of the Conference is Prof. K. Terzaghi and the secretary Prof. A. Casagrande. An organising committee has been appointed under the chairmanship of Ir. J. P. van Bruggen, with Ir. T. K. Huizinga as secretary and Ir. W. C. van Mierlo as treasurer. The Institution of Civil Engineers has convened a British National Committee under the chairmanship of Mr. W. K. Wallace, and full particulars of the Conference can be obtained from the Secretary, Institution of Civil Engineers, Great George Street, London, S.W.I.

Geotechnical properties of fresh municipal solid waste at Orchard Hills Landfill, USA.

Compressibility and shear strength of municipal solid waste under short-term leachate recirculation operations.

This paper presents a laboratory investigation of hydraulic conductivity of municipal solid waste (MSW) in landfills and provides a comparative assessment of measured hydraulic conductivity values with those reported in the literature based on laboratory and field studies. A series of laboratory tests was conducted using shredded fresh and landfilled MSW from the Orchard Hills landfill (Illinois, United States) using two different small-scale and large-scale rigid-wall permeameters and a small-scale triaxial permeameter. Fresh waste was collected from the working phase, while the landfilled waste was exhumed from a borehole in a landfill cell subjected to leachate recirculation for approximately 1.5 years. The hydraulic conductivity tests conducted on fresh MSW using small-scale rigid-wall permeameter resulted in a range of hydraulic conductivity 2.8× 10−3 –11.8× 10−3  cm/s with dry unit weight varied in a narrow range between 3.9–5.1 kN/ m3 . The landfilled MSW tested using the same permeameter produced ...

Hydraulic Conductivity of MSW in Landfills

An investigation of the variability associated with primary and secondary compression indices of municipal solid waste (MSW) is conducted in the present study. A controlled laboratory experimental program was conducted to quantify the compressibility of fresh MSW and landfilled MSW (subjected to leachate recirculation for a year in the field) under different elevated moisture content conditions. Several series of one-dimensional compressibility experiments were conducted on fresh and landfilled waste samples under the field moisture content of 44% (by dry weight) and three elevated moisture contents of 60, 80 and 100% (by dry weight). The compression of waste samples was measured at different elapsed time periods under incremental normal stresses of 48, 96, 192, 383, and 766 kPa. The modified compression indices (or compression ratios) were calculated based on the measured compression versus stress data. Long term secondary compression behavior was determined by performing long term compression tests on f...
