GEOPHYSICAL AND GEOTECHNICAL APPROACH TO CHARACTERIZE A CONSTRUCTION AND DEMOLITION WASTE

Research objectives: This study aims to determine the geological and geotechnical characteristics of an anthropogenic deposit, which consists of a construction and demolition waste landfill. Method overview: The method encompassed: mapping, with a sample collection was carried out; determinations of soil penetration resistance, with a dynamic penetrometer, which was used to determine the penetration resistance of the surface layers of the landfill and surrounding natural material areas; hydraulic conductivity determination; electrical resistivity property using geophysics and particle size analysis. The following data items were made available: 1. Geophysics: They content a list of apparent resistivity due to the heterogeneity of the medium. For the survey, five parallel lines were used. 2. Hydraulic conductivity: It contents a list with the results of measuring the water´s lowering speed. 3. Dynamic Penetrometer: They content a list of the penetration of the cone (centimeter) measured after each blow, for a total of 32 points. 4. Granulometric analyses: They content a list with the result of the complete granulometric analyses.研究目标： 本研究旨在明确以建筑与拆除废弃物填埋场为主体的人为堆积体的地质与岩土工程特性。 方法概述： 本次研究采用的方法包括：测绘与样品采集；采用动力触探仪（dynamic penetrometer）测定填埋场表层及周边天然土体区域的土体贯入阻力；渗透系数测定；采用地球物理方法开展电阻率特性测试，以及颗粒级配分析。 本次研究公开了以下数据集条目： 1. 地球物理（Geophysics）：包含反映介质非均质性的视电阻率数据集。本次探测共布设5条平行测线。 2. 渗透系数（Hydraulic conductivity）：包含水位降速的实测结果数据集。 3. 动力触探仪（Dynamic Penetrometer）：包含每一击后测得的锥尖贯入深度（单位：厘米）数据集，共覆盖32个测点。 4. 颗粒级配分析（Granulometric analyses）：包含完整的颗粒级配测试结果数据集。
