摘要
参数测定是包气带冻土研究的基础和难点,在分析已有研究的基础上,以综合质量含水量(含冰量与未冻水含量)、冻土温度为目标参数,立足野外原位监测,设计提出了以语音式低温地温计、冻土水热遥测装置、冻土水热简易监测装置为基础的监测方案,并结合黑龙江大学呼兰校区冻土水文试验场冻结条件下包气带土壤垂向水热实际试测结果,对监测方案进行了分析和评价。
Frozen vadose soil research is a key content in the development of cold region, Water and thermal parameters studies is the core content of frozen vadose soil research.This paper selects comprehensive quality content(ice content and the unfrozen water content)and soil temperature as the objective parameters.Based on the field monitoring,we put forward monitoring schemes mainly include voice type low-temperature geothermometer,frozen soil water and thermal automatic monitoring device,frozen soil water and thermal artificial monitoring device.We complete the scheme evaluation on the basis of freezing soil vertical hydrothermal actual test results in Harbin Hulan campus of Heilongjiang University.
