在对巴东县地质灾害进行详细调查的基础上,结合该县近年来地质灾害的发育情况,对巴东地质灾害的发育特征和分布规律进行了简要的分析。研究表明,该县地质灾害具有爆发频率高、突发性强、危害大、隐蔽性强的特点,其分布发育与区内复杂的地质环境条件和人类工程活动密切相关,在空间上集中分布在长江、清江及其支流两岸一级岸坡地段,在时间上集中在雨季和库水位降落期。
在對巴東縣地質災害進行詳細調查的基礎上,結閤該縣近年來地質災害的髮育情況,對巴東地質災害的髮育特徵和分佈規律進行瞭簡要的分析。研究錶明,該縣地質災害具有爆髮頻率高、突髮性彊、危害大、隱蔽性彊的特點,其分佈髮育與區內複雜的地質環境條件和人類工程活動密切相關,在空間上集中分佈在長江、清江及其支流兩岸一級岸坡地段,在時間上集中在雨季和庫水位降落期。

Based on the detailed investigation of geological hazards in Badong County and combined with its current status,this paper analyses the development characteristics and the occurrence cause of the geo-hazards.Through investigation,it is evident that geological hazards in this county break out frequently,occur suddenly,and have serious harm and strong concealment.The development and distribution of geological hazards closely relate to the complicated geological environment and human activity in this region.The spatial distribution of geological hazards is mainly along slope of Yangtze River,Qingjiang River and their tributaries.Geological hazards often occur in rainy seasons,or during the falling of reservoir lever.
