Temperature is one of the key factors affecting the permeability of water flow in loess, influencing its stability and, consequently, its geohazard potential. The traditional temperature calibration formula(TTCF) is widely used in the literature for calculating the permeability at some temperature, based on the permeability at 20 °C. However, its suitability has not been verified, especially for water flow in loess. The influence of temperature on the permeability of loess and the suitability of the TTCF were examined using samples of the late-Pleistocene Malan loess, the most widely distributed loess in the Chinese Loess Plateau, as the subject. The temperature dependency of the saturated permeability of remolded loess was investigated using the constant head permeability test method over a temperature range of 0 to 40 °C. The results show that the permeability of remolded loess increases with temperature, but in a nonlinear manner. Between 0 and 4 °C, although the changes are small, and at around 25 °C, there may be an important change in the soil's structure. We found that the measured values of loess permeability deviate strongly from those calculated by the TTCF, especially over the temperature range 0 to 4 °C and > 25 °C. New formulas for the calibration of temperature effects on the permeability of loess have subsequently been developed. Also, an empirical model for predicting the saturated hydraulic conductivity was inferred, which can satisfactorily reflect the temperature and compactness effects on permeability. The results of this study may be employed for projecting the effects of temperature changes into loess engineering and in assessing geohazard potential.

温度是影响黄土中水渗透性，影响其稳定性并进而影响其地质灾害潜力的关键因素之一。传统的温度校准公式（TTCF）在文献中被广泛用于基于20°C的磁导率来计算某个温度下的磁导率。但是，其适用性尚未得到验证，特别是对于黄土中的水流。以晚更新世的马兰黄土为样本，研究了温度对黄土渗透性和TTCF适用性的影响。使用恒定水头渗透率测试方法在0至40°C的温度范围内研究了重塑黄土的饱和渗透率对温度的依赖性。结果表明，重塑黄土的渗透率随温度升高而增加，但呈非线性关系。在0到4°C之间，尽管变化很小，但在25°C左右，土壤的结构可能发生了重要变化。我们发现，黄土渗透率的测量值与TTCF计算得出的值有很大偏差，尤其是在0至4°C且> 25°C的温度范围内。随后开发了校准温度对黄土渗透性影响的新公式。此外，推导了预测饱和水力传导率的经验模型，该模型可以令人满意地反映温度和压实度对渗透率的影响。
