摘要:
拦挡坝的破损研究是困扰泥石流治理工程的主要难点之一,分析总结拦挡坝破损原因,优化其设计理念十分重要。本文对陇南市武都区16条沟道的65道泥石流拦挡坝破损形式及导致坝体破损的相关条件进行详细调查和统计分析。结果表明:(1)拦挡坝破损形式主要有以下几种(按破损概率由大到小排序),依次为副坝破损、坝肩破损、溢流口破损、基础破损、冲毁(失去功能)、勾缝破损;(2)根据拦挡坝破损特征统计分析,确定其破损主要与泥石流性质、圬工材料、坝体高度、坝体选址、坝肩保护、基础保护和库容淤积等情况有关;(3)导致拦挡坝破损的主要原因总结为对沟道机理认识不足、坝体自身存在缺陷和保护措施不当。在此基础上,从理论研究、工程管理、拦挡坝体系设计、新技术新方法应用等方面着手,提出了拦挡坝防治工程优化对策。
