| 摘 要： | 以相关领域关于土体蒸发模型研究成果为基础，结合岩土工程蒸发过程的特点，对确定土体潜在蒸发量方法的发展及现状进行介绍，并对每种理论模型的适用条件及参数的确定等进行分析。结果显示：（1）特定的地区、气候条件下，通过多种理论模型对比分析，确定相对合适的理论模型估算潜在蒸发量是必要的。（2）气象参数的区域性很明显，即使是具有相似气候特征的小区域，不同气象站提供的气象资料反演的气象参数也不相同，故根据气象资料反演得到的气象参数要进行修正。（3）现有蒸发测量技术应用于岩土工程的蒸发测量中有待进一步深入研究发展。提出该课题在岩土工程领域今后的研究方向，包括土体稳定蒸发阶段蒸发机制、蒸发的滞后效应、夜间土体水分变化对蒸发的影响、通用蒸发模型的建立及实测蒸发量的尺度效应等。

| Abstract: | Based on the research achievements on potential evaporation model for soil moisture in related disciplines,and combining with the characteristics of evaporation process in geotechnical engineering field,the advances on determining potential evaporation of soil moisture are summarized,and the application conditions and how to determine the parameters in estimating potential evaporation are analyzed.The knowledge is shown as follows:(1) Under specific climate condition in specific regions,it is necessary to select relatively appropriate theoretical model to estimate potential evaporation by comparing various theoretical models. (2) Meteorological parameters are regional obviously,even in a small region with fairly similar climates,different inversion meteorological parameters could be drawn with meteorological data from different stations,so inversion meteorological parameters should be calibrated. (3) A thorough study should be performed for evaporation measurement technology in geotechnical engineering field.The research topics in geotechnical engineering field in future are provided,including the evaporation mechanism of stable stage,the hysteresis effect of evaporation,the effect of moisture change on evaporation at night,construction of universal soil moisture evaporation theoretical model and the scale effect of evaporation measurement. |
