摘要
SDG无核土壤密度仪是一种无损快速填土压实度检测装置,可用于压实填土密实度的快速无损检测。在了解SDG无核土壤密度仪的工作原理和确定测试所需的前置参数设定的基础上,通过现场传统灌砂法和SDG测试法的对比试验及室内模拟试验,对SDG密度仪在压实填土密实度快速检测的适用性和可靠性进行了研究,重点考察了填土含水条件和密实程度对测试结果的影响,为SDG密度仪在工程上的应用作出了有益探讨。
SDG,a non-nuclear soil density gauge,is a nondestructive and high-speed device to test the compaction of the soil-filling density.Based on the understanding of the SDG working principles and needed pre-set parameters,the paper defined the applicability and reliability of SDG rapid testing the compacted soil density by comparing between the conventional sand-filling method and SDG and the indoor simulation tests.The paper focused on the influence of water conditions and compaction situations on the test result,which established a foundation for SDG application in the engineering project.
