小浪底水库是黄河中游的一个大型水利工程,坝高152米,库容126.5亿米~3。地质条件极为复杂,水库地震是许多工程地质问题中的一个重要问题。本文依据库区的地层岩性、地质构造及水文地质条件等方面,将小浪底水库区分为三个区段进行讨论,认为小浪底水库诱发震的最危险地段在水库区的中段,但最大强度一般不会大于5.5级,对大坝区的影响烈度也不会超过6度.
Xiaolangdi Reservoir is a large-scale water conservancy project in the middle reaches of the Yellow River, with a dam height of 152 meters and a storage capacity of 12.65 billion meters ~ 3. The geological conditions are extremely complicated. Reservoir earthquakes are an important issue in many engineering geological problems. Based on the stratigraphic lithology, geological structure and hydrogeological conditions in the reservoir area, this paper divides the Xiaolangdi Reservoir into three sections and discusses that the most dangerous section induced by Xiaolangdi Reservoir is in the middle of the reservoir area, but the maximum intensity is generally not Will be greater than 5.5, the dam area will not affect the intensity of more than 6 degrees.
