Geosynthetic Modelig System-CSC Version 1.00. GM System User's Manual

摘要

The development of guidance design procedures for the evaluation of geosynthetic materials used in containment systems for landfills, surface impoundments and waste piles has been computerized to increase the speed of calculation of results and to reduce the frequency of human error resulting from manual calculations. Potential failure modes for each geosynthetic component are established. A design procedure is developed for evaluating each of the potential failure modes. Each design procedure is based on calculation of service conditions in the component under field conditions. A Design Ratio (DR) is then calculated as the ratio of the limiting performance of the component based on laboratory tests to the actual performance calculated for field conditions. Minimum values for Design Ratio are recommended for each design procedure. Specific geosynthetic material properties are required to determine the DR in each design procedure. A suggested range of values, based on available data, is presented for each material property used.
