Abstract: This paper deals with the results of pressure and solution tests on rock samples in order to provide an experimental basis for earthquake prediction using radon anomalies. Based upon the general determinations of radon concentration in ground water from the Tangshan area, the authors on the samples collected from the wall rocks and wells made a comprehensive study of the uranium (thorium) content in the rocks and the relationship between the radon concentrations which were escaping from the broken rocks by pressure ordis solving in water and existing in wells. The authors suggest that the higher the content of radioactive element in wall rocks of the wells is, the larger the escaping radon amount from the broken rocks; the more the radon amount solved in water of the broken rocks and the higher the radon concentrations in ground water of the wells will be.

摘要： 有关氡气的来源、变化机制及共和地应力的关系尚处于研究过程中。本文将围绕这一问题对岩石标本进行压力试验和溶解试验,为氡预报地震的压溶机制提供实验依据。作者在对唐山地区水氡普查测定的基础上,采集井孔围岩及岩芯标本,开展岩石铀(钍)含量、岩石压氡、岩石水溶解氡及井孔水氡含量之间的综合研究。初步认为,当岩石受压变形破裂时井孔围岩中放射性元素的含量与氡逸出量呈正向关系。
