摘　　要：沅麻盆地是湖南省主要的大型红层盆地之一,沅麻盆地红层区"岩水"作用易发生膨胀和崩解,通过对麻阳县红层区地质灾害的研究和强降雨对沅麻盆地红层区的影响分析,总结出沅麻盆地红层区地质灾害发育特征及成灾规律。The Yuanma basin is one of the major large red basins in Hunan Province. The ＂rock-water＂ effect in the red bed of Yuanma basin is easy to expand and collapse. Through the study of the geological hazards in the red bed of Mayang County and analysis on the influence of heavy rain in red bed of Yuanma basin, summarizes the characteristics of the geological hazards development and the law of disaster in the red bed of Yuanma basin.
