| 摘 要： | 在青藏高原东部温泉地区对多年冻土厚度探测进行了试验研究,总结出一套可行的用于探测0～100 m范围内多年冻土分布及厚度的探测方法:选用探地雷达及瞬变电磁测深法分别对冻土上限及冻土下限进行探测,探地雷达分辨率高,能够有效解决地下0～5 m范围内多年冻土是否存在及上限埋深情况,而瞬变电磁测深法能有效解决地下5～100 m范围内的多年冻土下限埋深情况。

| Abstract: | The exploration of permafrost thickness refers to determining the upper and the lower limits of frozen soil depth.According to the geophysical properties of permafrost,frozen and non-frozen soils show significant differences in the permittivity and resistivity.Using ground penetrating radar(GPR) and transient electromagnetic sounding method(TEM) respectively,the authors explored the upper and the lower limits of permafrost in hot spring areas of eastern Tibetan Plateau.The results show that GPR and TEM can ... |
