四川省主要水系流域的地震监测

四川省分布着金沙江、雅砻江、大渡河、岷江、沱江、涪江、嘉陵江和渠江等8大水系。由于金沙江、雅砻江和大渡河等流域的水电站基本处于高海拔、高地震烈度、高边坡和地质条件复杂的高山峡谷中,据相关法律法规,有必要加强水电站地震监测。经30多年的努力,8大水系共计16个电站建成专用地震监测台网并投入运行,其余56座电站的地震监测工作推进较缓,文中对四川省主要水系流域地震监测情况予以详细阐述,希望为地震监测工作推进缓慢的流域提供参考,促进地震监测工作的顺利实施。

The seismic monitoring of main watersheds in Sichuan Province

There are 8 main water systems in Sichuan Province, including Jinsha river, Yalong river, Dadu river, Minjiang river, Tuojiang river, Fujiang river, Jialing river, and Qujiang river. Because hydroelectric power stations located on the Jinsha river, Yalong river, and Dadu river are basically in high altitude, high seismic intensity, high slope, and mountain canyon with extremely complex geological conditions, it is necessary to strengthen seismic monitoring of hydroelectric power stations according to relevant laws and regulations. After more than 30 years of efforts, a total of 16 power stations located on the eight water systems have built special seismic monitoring networks and put into operation, while the other 56 power stations have made slow progress in seismic monitoring. This paper describes the situation of seismic monitoring in the main river basins of Sichuan Province in detail. It is hoped that the river basins with the slow progress of earthquake monitoring will promote seismic monitoring as soon as possible.
