摘　　要：土体水分的蒸发对土工建筑物的安全与工作性能具有重大的影响。深入研究土体水分蒸发机理及其影响,对预防和解决由蒸发引起的灾害问题具有重要的现实意义。在查阅大量文献的基础上,系统地阐述了蒸发皿、蒸渗仪、土柱(盒)装置、风洞和环境箱等土体蒸发试验装置的特点和适用范围,为今后进行相关的试验研究提供了有益的参考。Water evaporation from soil has significant influence on the safety and performance of various earth structures, hence better understanding the mechanism and effects thereof has practical meaning for preventing and solving the hazards therefrom. Based on the reference to many literatures, the characteristics and the scope of application of various devices for the water evaporation test （e. g. , evaporation pan, lysimeter, soil column apparatus, wind tunnel and environmental chamber） were introduced systematically, which could be referred to in the later experimental study.
