1、摘要施工导流是保护水利水电工程在干涸河床正常施工，控制河水下泄所采取的工程措施。施工导流设计是水利水电枢纽总体设计的重要组成部分，是影响坝址选择、枢纽布置、永久建筑物型式、施工程序和施工进度的重要因素。本设计依据《水利水电工程施工组织设计规范》（SDJ338-89）第二章施工导流的有关规定编写。在对坝址区域的地形、地质资料，水文气象资料分析的基础上通过对堰型、隧洞型的定性分析比较，定出隧洞轴线、堰轴线的位置。由于坝址附近有丰富的料场，并且距坝址较近，交通运输较方便等，综合考虑最终拟建上游为土石坝围堰、下游为土石坝围堰。该工程主要由上下游围堰、导流隧洞等组成。

2、设计确定上游围堰的堰顶高程为450.50m，堰顶宽为5.00m，堰高为40.50m，下游围堰的堰顶高程为427.00m，堰顶宽为3.00m，堰高为17.00m，隧洞底高程为418.00m，隧洞宽为15.00m，隧洞高17.500m，隧洞坡降为0.001，进口长为50.00m，洞身长为500.00m，出口长为50.00m，并采用扩散消能。设计最终成果：说明书一份、计算书一份、设计图纸4张及其他计算附图和附表等。关键词：施工导流、围堰、截流、进度控制、混凝土、土石坝56AbstractTheconstructiondiversionisprotectwaterc
