长江三峡黄腊石滑坡地表排水工程

SURFACE DRAINAGE ENGINEERING FOR HUANGLASHI LANDSLIDE IN SANXIA,YANGTZE RIVER BASIN

排水是常用的滑坡治理措施，合理的排水措施可有效地防止滑坡活动，布置不当则效果不大。本文根据黄腊石滑坡特征及其稳定性影响因素，滑坡区坡面径流及入渗规律的分析，介绍了地表排水沟的布置原则和结构形式。

The drainage is a common measure of landslide administer. Suitable drainage measure can effectively prevent landslide activity, but the effect is not well if unsuitable. To account the characters of Huanglashi landslide and factor influencing its stability, and based on the analysis of law of slope runoff and influent seepage in landslide area, the arrangement principle and structure mode of surface drainage ditch was introduced in this paper.
