| 摘 要： | 系统地阐述了测量圆锥指数CI用的圆锥仪在国内外的发展概况。在工兵圆锥仪和电测圆锥、剪切仪第一代样机的基础上,研制了一种用微型电动机作动力的自动化程度较高的高精度电测圆锥仪。该仪器能现场打印出与深度Z相对应的土壤的CI值、整个测试深度内土壤的平均CI值及Z—CI曲线。着重介绍了该仪器的组成、性能及技术特点。通过试验证明,该仪器测试可靠,精度高,操作方便。

| Abstract: | As a comprehensive characteristic of the mechanical strength of soil, the coneindex (CI) has been widely used. On the basis of reviewing the history and the development ofcone penetrometer, an automatic electronical cone penetrometer which is powered by a small re-versible electric motor is developed. The measured CI value corresponding with depth, average CIvalue and the CI-Z curve can be printed out on the spot. Test results show that it has high mea-sure precision, reliability and automation. |
