摘    要:通过对当地地形地貌、暴雨特征、流域面积、地层岩性、地质构造、水文地质条件、泥石流物源的调查与分析研究,针对该泥石流具有危险度高、流量大、流速缓的特点,结合受灾对象及其分布区域与整体布局和局部治理的关系,按照防治结合、因地制宜、突出重点的原则设置了拦挡滞洪、导流防护、漫水路相结合的综合防治工程措施。拦挡工程为有效发挥工程泻洪、拦渣、调节、固床、稳坡和控制固体物质补给量,预防沟道下切及沟壑发展,减少泥石流对下游村庄危害,起到了积极作用;通过导流堤的建筑限制泥石流的流速、流向,将泥石流顺畅地通过受灾对象比较集中的区域,排入下游非危害区;漫水路为当地群众出行提供方便,又是应急通道。工程实施后综合效益明显。

关 键 词:贾楼  流域  泥石流  暴雨  水文地质  灾害  综合防治措施  河南泌阳县
