龙羊峡水电站大坝两岸绕渗观测分析

ANALYSIS OF SEEPAGE AROUND DAM SHOULDERS AT LONGYANGXIA HYDROPOWER PLANT

概要介绍了龙羊峡水电站坝址区的工程地质和水文地质特性，对两岸地下水位进行了统计、比较分析，得出了基本的规律性。文章指出施工用水是两岸地下水位抬升的重要原因。并指出可能存在着的集中渗漏通道，供令后管理工作参考。

This paper gives an introduction to the characteristics of engineering geology and hydrogeology at the damsite of the Longyangxia Hydropower Plant. and makes a statistical comparative analysis of the groundwater at the two river--banks. and then derives a basic regulation. It is pointed out that the water for construction is the main factor leading to the groundwater level rise. and that a concentrated infiltration access probably exists. This paper may be useful for the managernent of the dam.
