摘要
宝珠寺水库自蓄水以来由于库水的反复升降及暴雨作用,库区沿岸发生了较大面积的滑坡,库区许多交通等基础设施,迁建集镇、移民房屋遭到破坏,对沿岸经济发展及社会稳定造成严重影响。文章在对库区滑坡分布特征、类型、形成条件、形成机制及其活动特征分析基础上,以库岸地形特征、地质条件、岸坡岩土次生改造作用、库水升降影响、人类工程活动及岸坡集水面积6个指标为参数,对库岸稳定程度进行了聚类分析。结果表明,宝珠寺水库沿岸岸坡约有4%处于稳定状态,70%处于较稳定状态,20%处于较不稳定状态,其余处于不稳定状态。
Because of Baozhusi reservoir water repeatedly raising and falling and rainstorms since the reservoir sluice, wholesale geological disasters, such as landslides and mudflows, have occurred along the bank of Baozhusi reservoir. The landslides have serious influence on economy development and society stable due to many communication projects, electric power facilities, newly-buih immigration town and immigration houses were destroyed. Based on the investigation and testing data from the field, the distribution features, types, formating condition and mechanism, sliding tendency and potential disaster of the landslides around the reservoir were analyzed in this paper. The geological environment conditions and stability of the bank slopes around the reservoir were accessed and, mapped in order to provide countermeasures to the local government.
