【摘要】 本文简述了在中国建立土壤参数标准的必要性,分析了地面—机器系统力学中所用的十组土壤参数,认为采用圆锥指数CI值作为土壤参数标准较为合理。提出了新的测定水田表层及其松软土壤(CI=0-10 kN/m~2)参数的方法、原理、并提出测定极坚实土壤(CI>3000kN/m~2)参数的方法。改制出便携式仪器样品,进行了土壤圆锥指数测定试验,证明效果良好,为正式设计、制造这种宽量程仪器提供了依据。更多还原

【Abstract】 This paper briefly discusses the necessity of estabilishing the soil parameter standard in China. By analyzing ten groups of soil parameters which used in the terra-machanics, it deams that the cone-index (CJ) value is more rational to be used as the standard soil parameter.In order to enable a portable instrument to measure the various aad complex me-chanical properties of soil, the authors develop a new principle for measuring the extremely soft topsoil of the paddy-field (CI=0-10kN/m2), and the method for measuring the extremely hard and drieded soil in the field (CI>3000 kN/m2).Further more, the authors have reformed a model, which have been demonstrated to have good effects through test. Thus the basis of designing and building this wide range cone-iadex measuring instrument has been provided.更多还原
