The compaction control of earth works is an essential task in geotechnical engineering. In order to build more sustainably and to reduce project costs, fine-grained materials are more often used for embankment construction nowadays. The quality control of compacted soil layers is usually defined in terms of deformation moduli obtained from static and dynamic plate load tests or based on the degree of compaction, which is generally related to the Proctor density. Penetration tests, such as cone penetration tests (CPT), seismic flat dilatometer tests (SDMT) or dynamic probings (medium heavy dynamic probings (DPM)), show a potential for assessing the compaction along vertical profiles but no standardized quality criteria have been elaborated yet. The present work investigates the effects of different water contents and degrees of soil stabilization on results of CPT, SDMT, DPM, plate load tests and Proctor tests for an 8 m high trial embankment, characterized by a clayey to silty material. CPT and DMT results were found to strongly correlate with deformation moduli of static and dynamic plate load tests, enabling the definition of new quality criteria for compaction control.

使用渗透试验控制细粒路堤的质量

土方工程的压实控制是岩土工程中的一项重要任务。为了更可持续地建设并降低项目成本，如今路堤建设更常使用细粒材料。压实土层的质量控制通常根据静态和动态板载荷试验获得的变形模量或基于压实程度来定义，压实程度通常与 Proctor 密度相关。贯入试验，例如锥入度试验 (CPT)、地震平板膨胀仪试验 (SDMT) 或动态探测（中重型动态探测 (DPM)），显示出评估沿垂直剖面的压实度的潜力，但尚未制定标准化的质量标准然而。目前的工作研究了不同含水量和土壤稳定程度对 CPT、SDMT、DPM、平板荷载试验和 Proctor 试验结果的影响，该试验针对 8 m 高的试验路堤，其特征为粘土至粉质材料。研究发现 CPT 和 DMT 结果与静态和动态板载荷测试的变形模量密切相关，从而能够定义压实控制的新质量标准。
