1目的和范围1。1建议使用土壤锥贯入仪（图1）作为测量设备，以提供表征土壤贯入阻力的标准统一方法。按30°所需的力 通过土壤的圆锥体，以千帕斯卡表示，是土壤强度的一个指数，称为锥体指数。1.2本标准旨在实现以下目的:1.2.1提供一种通用方法，用于构建能够测量一般土壤力学条件的装置，方便不同研究人员报告和解释土壤数据。1.2.2协助在不同土壤和土壤条件下工作的人员，以及需要测量土壤机械性能以进行比较的人员。1.2.3提供表征土壤性质的通用系统，从中可以建立性能和预测关系。1.3本标准仅作为建造测量土壤抗渗透性的装置的手段，不提供具体的土壤值，如粘聚力、摩擦角或土壤系数- 金属摩擦。 由于测量结果受使用方法的影响，用户应参考ASAE EP542。

1 Purpose and Scope1.1The soil cone penetrometer (Figure 1) is recommended as a measuring device to provide a standard uniform method of characterizing the penetration resistance of soils. The force required to press the 30° circular cone through the soil, expressed in kilopascals, is an index of soil strength called the cone index.1.2The Standard is intended for the following purposes:1.2.1To provide a common method of constructing a device capable of measuring general soil mechanical conditions that facilitates the reporting and interpretation of soil data by different research workers.1.2.2To assist those who work with different soils and soil conditions and who need a measure of soil mechanical properties for comparative purposes.1.2.3To provide a common system of characterizing soil properties from which it may be possible to develop performance and prediction relationships.1.3The Standard serves only as a means of constructing a device to measure soil resistance to penetration, and does not provide specific soil values such as cohesion, angle of friction or coefficient of soil-metal friction. Since the measured results are influenced by the method of use, users should refer to ASAE EP542.
