地壳形变资料物理性质的论证及分析

PHYSIC FEATURES OF DEFORMATION DATA DEMONSTRATED AND ANALYZED

本文研究了地壳形变资料中出现的各种突出变化和长期变化,比较了在同一地点不同深度地层所观测到的形变量,得出的结论是:形变资料的变化主要是由于地层中所含的水和温度变化造成的。当地层中水和温度的量值变化时,地层便膨胀或收缩,依附于地层的形变测量标志也就随之而被移动。因此,不应把形变资料就作为深部地层的形变信息。 本文还提出了一些鉴别由于地层含水和温度的变化所导致的资料异常的方法。

Various outstanding and long-term changes in the deformation data were studied and the deformation values observed at different depths at the same location were compared in this paper. It is concluded that the variation of the deformation data is mainly caused by the changes of the water and temperature contained in the layers. When the content of water and temperature in the layers changes, the layers expand and contract and the measure mark of deformation is also moved. Therefore, The deformation data should not be regarded as the deformation signal in the deep layers.This paper also gives some methods in distinguishing data anomallies caused by the changes of water and temperature contained in the layers.
