我国工程地震研究的开拓者——谷德振先生

DEVELOPMENT SCHOLAR OF RESEARCH OF ENGINEERING EARTHQUAKE IN CHINA—MR.GU DEZHEN

系统查阅谷德振先生的生前论著,发现他不仅是国内外著名的工程地质学家,而且还是我国工程地震研究的开拓者。早在治淮工程开始就注意工程建设中的地震问题,1959年新丰江水库诱发地震后,特别关注工程地震问题,提出了工程区域地震稳定性评价的科学思路与技术方法,提出了活动断层的新概念,建议把晚更新世以来活动断裂称为活断层,并提出了从区域构造发展历史出发识别活断层的方法,提出了水库诱发地震是水库水体荷载与沿断裂带库水下渗引起的强度弱化和孔隙压力共同作用的科学观点等。他把上述观点、思路与方法,成功应用到新丰江水库诱发地震治理、葛洲坝工程与丹江口工程坝址勘选等一系列重大工程实践之中。

On the basis of consulting treatises of Mr.Gu Dezhen before his death,it is discovered that he not only is a wellknown scholar of engineering geology at home and abroad,but is a development scholar of research of engineering earthquake in China.He started to follow with interest the earthquake problems in engineering construction since the engineering of harnessing Huai river as early as 1951,and specially focused on the problems of engineering earthquake since the Xinfengjiang reservoir induced earthquake at 1959.He presented the scientifically thins and technical methods on evaluation of earthquake safety in engineering area.He presented new conception on active fault,and suggested to call all the active fracture since late pleistocence as active fault.He also put forward that identification active fault start from regional tectonic development history.He presented the scientifically point on genetic mechanism of reservoir induced earthquake,which combined effect of water loading, strong weakening and pore pressure caused by water infliction along fault zone.Mr.Gu applied above points,thinks and methods successfully to a series of great engineering practices,for example harnessing of Xinfengjiang reservoir induced earthquake,dam site selection and investigation of Gezhouba and Danjiangkou reservoir,etc.
