EVALUATION METHOD FOR WATER SEALING PERFORMANCE OF MULTILAYER COVER SOIL AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method for water insulation performance of multilayer cover soil and device therefor that can evaluate the water sealing performance of a soil layer formed out of coarse grain soil and fine grain soil constituting the coarse grain layer and fine grain layer of a multilayer cover soil.;SOLUTION: The evaluation method in which, by performing a test using a two-dimensional test tank with the coarse grain soil and fine grain soil to be used filled in layers to the multiple cover layer formed by filling the coarse grain soil, fine grain soil, and field-generated soil in order of lower position on the upper surface of landfilled solid waste, the flow data of penetrating water is measured, is characterized in that the property values of the coarse grain soil and fine grain soil are determined by reversely analyzing the measured flow data, and then the water sealing performance of the soil layer formed with the coarse grain soil and fine grain soil is analyzed and evaluated based on the determined property values.;COPYRIGHT: (C)2003,JPO
