| 摘 要： | 多年冻土的上下限是在多年冻土区从事冻土研究、工程设计施工、气候水文生态模式等方面非常重要的参数,它可以通过破坏环境的有损方法(坑探和钻孔)或无损的物探方法来获取.结合少量的坑探和钻孔资料,应用瞬变电磁法(TEM)对青海省兴海县温泉地区多年冻土进行探测.基本查清了本地区多年冻土分布特征、上下限深度和多年冻土层的厚度,获取...

| Abstract: | The permafrost table and base are two of the most important geological variables in near-surface deposits in the continuous permafrost regions,and they are possibly to be determined either by invasive and environmentally destructive techniques(excavation and drilling) or noninvasive low-impact geophysical methods.Geophysical techniques are the most effective way to examine the spatial distribution of subsurface geophysical properties to reveal the active layer and permafrost layer horizontally and verticall... |
