近年来作者在进行“黄土坡面产流实验与模拟的研究”等课题的研究中,研制了室内一维土柱入渗装置系统。该系统对于均质扰动土柱及原状土柱,在降雨入渗或积水入渗条件下的入渗率以及土壤水在剖面上的分布,分别采用了自动跟踪测量和放射性同位素测量,并利用计算机对数据进行实时釆集和处理,提高了量测精度,减少了人为差错,同时又便利了试验资料的整理分析,因而,为非饱和土壤水运动的试验研究提供了先进的测试手段。该试验装置系统的组成见图1所示。
In recent years, the author carried out the “Loess slope runoff experiment and simulation studies” and other topics of research, developed a one-dimensional indoor soil column infiltration device system. The system uses automatic tracking measurement and radioisotope measurement for the disturbed soil column and undisturbed soil column, the infiltration rate under the conditions of rainfall infiltration or seepage, and the distribution of soil water in the cross section. Computer real-time data collection and processing to improve the measurement accuracy, reducing human error, but also facilitate the sorting and analysis of test data, and therefore, to provide an advanced test means for the experimental study of unsaturated soil water movement. The experimental setup is shown in Figure 1.
