| 中文摘要: |
| 自制了一套用于研究温度作用下土体水分传输机制的室内试验模拟系统。采用水浴加热替代电阻丝直接加热的方案,解决加热不均匀且不容易控制温度的难题。应用串行通讯接口技术把智能温度控制仪表和微机连接,实现了温度自动控制和采集的自动化。开展了7组试验耗时接近1年,试验结果表明,该系统性能稳定、部件之间兼容性较好,连续工作30天温度的波动范围在±1℃内,证明该试验系统可用于模拟温度作用下土体的水分传输过程。 |
| 英文摘要: |
| An indoor experimental simulation system was home-designed and fabricated to study moisture transport mechanism in soil at different temperatures. By using water bath heating instead of resistance wire heating directly, the puzzle of uneven and uneasy temperature controlling was solved. In order to control and acquire temperature data automatically, Serial Communication Interface Technology was adopted to link intelligent temperature control instrument with PC. It took nearly one year to carry out 7 groups of experiment. Results show that this experimental system is stable and compatible; the temperature fluctuation range is within ±1℃ during 30 days. So this experimental system can be used to simulate moisture transfer process in soil under temperature effect. |
