液限的确定对土的工程分类和公路路基压实度控制标准的选择具有重要意义。基于液限试验中落锥试验中抗剪强度与贯入深度关系的研究成果，根据能量守恒定律对贯入过程进行分析，推导出K的表达式。然后，利用不同学者的实验数据和各国、各机构的现有数据对该表达式进行了验证。并与前人用极限平衡理论所得结果进行了比较。结果表明，新的表达式与实验结果吻合较好。K可以很好地预测。因此，可以根据锥贯入深度计算抗剪强度，然后通过室内试验将抗剪强度的实验值与计算值进行比较。分析了锥重和锥角对抗剪强度计算的影响。此外，根据K的表达式，对不同标准的液限指标进行了讨论，并对如何实现不同规范和标准的相对结合提出了建议，这对国际交流很有帮助。
The determination of liquid limit is of great significance in the engineering classification of soil and the selection of the control standard of highway subgrade packing and compactness. Based on the research achievements of many scholars on the relationship between the shear strength and the depth of cone penetration in fall cone tests in the liquid limit tests, the process of penetration was analyzed according to the Law of Conservation of Energy, and the expression of K was derived. Then, the expression was verified by the experimental data of different scholars and the existing data of various countries and institutions. And, the results were also compared with those obtained by the previous scholars using limit equilibrium theory. The results indicate that the new expression is in good agreement with the experimental results. K can be predicted well. And so, the shear strength can be calculated based on the depth of cone penetration, and then, the experimental value of the shear strength can be compared with the calculated value through laboratory tests. The influence of cone weight and cone angle on the shear strength calculation was analyzed. In addition, the liquid limit index of different standards was discussed based on the expression of K, and suggestions on how to achieve relative combination of different codes and standards were raised, which was very helpful for international communication.
