1、青海省互助县泽林峡水库左岸导流放水洞设计摘要导流洞是一个临时的施工导流隧洞，它的特点之一是工期往往是很紧迫的，如果不能按期完成，就会造成整个工程的工期延长。水库运行时利用放水钢管对下游进行灌溉、人饮供水、生态基流放水并兼顾水库放空。因此，一定要根据现场的地质、地形情况，枢纽的规划任务，按照一洞多用的原则，恰当的采用的各建筑物布置形式。这样既可减小工程量、降低造价、有利于整个工程的流水行作业，又可大大提高工程进度。本设计依据对互助县泽林峡水库的两岸地质地形、水文等资料的研究总结，在水库左岸将导流洞与放水洞合一布置，将临时性的导流隧洞部分封堵改建为永久放水隧洞。在整个工程施工过程中用
2、导流洞担任导流任务，待大坝挡水时将导流洞与放水洞衔接部位封堵，放水洞开始担任灌溉、人饮供水、生态基流放水并兼顾水库放空等任务。泽林峡水库左岸导流泄洪洞设计流程为：水文地质和气象和两岸地质条件等资料的考察→总结设计所需基本资料→参考设计规范→导流洞部分设计→放水洞部分设计→下游消能防冲设计。各设计包括必要的水力计算、消能计算等计算说明。最终得出一套完整的导流放水洞以及上下游围堰图纸。关键词：导流放水洞，水力计算，消能计算，体型设计HuzhucountyofqinghaiprovincezeLinXiaintheleftbankofthereservoirdiversiontunne
