广西中小型水电站工程地质勘察需注意的一些问题

Some issues in need of special attention for engineering geological survey of mid-and small-scale hydropower stations in Guangxi

针对中小型水电站具有坝低库小、水库条件简单、水库淹没及工程占地少,引水隧洞长而小、水头高、设计要求高,勘察周期短、费用少等特点,结合1年来对广西27座中小型水电站勘察成果的分析研究,提出了中小型水电站地质勘察应注意的一些问题。

In view of the characteristics of mid- and small-scale hydropower stations such as small dam height, small reservoir capacity, simple reservoir conditions, less reservoir inundated area and construction land area, long and small diversion tunnel, high water head, strict design requirement, short survey period and less cost and so on, combined with the analysis and research on the survey achievements of 27 mid- and small-scale hydropower stations in Guangxi in the past 1 year, the author put forward some issues in need of special attention for engineering geological survey of mid- and small-scale hydropower stations.
