摘要
在青藏铁路的建设过程中 ,多年冻土是一个关键问题 ,开展物探工作时 ,会遇到较非冻结区更为复杂和多变的勘测对象 ,因此 ,选择合理的工作方法就显得尤为重要。作者论述了目前开展的各种物探方法的优劣 ,给出了利用综合物探方法勘察青藏铁路多年冻土的结果。实践证明 ,开展综合物探是勘探多年冻土的一种行之有效的方法。
During the construction of the Qinghai-Tibet Railway, the perpetually frozen ground constitutes a key problem. The geophysical exploration will meet more complex and changeable objects in the perpetually frozen ground area than in the non-frozen area. Hence, the selection of rational working methods seems to be especially important. Based on a discussion on the strong and weak points of various currently-used geophysical techniques, the author advances the idea of integrated geophysical exploration with the enumeration of some practical examples. Practice shows that the integrated geophysical exploration is an effective means in the exploration of perpetually frozen ground.
