摘要： 随着社会经济的发展，人类工程活动日趋强烈，地质灾害呈加剧趋势。以湖南省国土资源厅下达的1∶5万地质灾害调查项目为基础,通过对益阳市南县、资阳54处管涌进行统计，并结合对南县和资阳两处管涌渗透层的取样实验结果，提出洞庭湖区管涌的防治距离以距大堤外坡脚15H更为合适。调查结果可为洞庭湖湖区管涌地质灾害的防治与治理提供参考依据。

Abstract: Geohazard occurrence frequency increases with the social economic development and engineering activities. Geohazards could seriously affect the properties, human safety as well as social sustainable development. This paper presents the 1:50,000 scale geological investigation results of 54 piping locations in Nanxian and Ziyang, Yiyang City. Soil samples were collected from the two piping locations with each at Nanxian and Ziyang and laboratory tested. It is concluded that the piping preventive measures should be within 15H away from the toe for levees in Dongting area. These investigation results can provide information in minimizing the piping hazards in Dongting area.
