本文结合液限试验原理,通过分析得出由于不同标准中对圆锥质量、锥体下沉深度、划刀尺寸和底座硬度要求不尽相同,导致了不同标准下测得土体液限值有所差异。通过实例验证说明建立的相关性数学模型具有较高的准确性和拟合精度,可以满足对液限值的精度要求,具有很强的应用性。 Based on the principle of liquid limit test, the analytical results show that due to the different requirements of the conical quality, the cone sinking depth, the size of the cutter and the hardness of the base, the liquid limits of the soils obtained under different standards are different . The experimental results show that the established mathematical model of correlation has high accuracy and fitting accuracy, which can meet the accuracy requirements of the liquid limit and has strong applicability.
