摘　　要：基于长江的第一大支流汉江河道宽、流量大、河床基础稳定性差等特点,以汉江碾盘山水利水电枢纽工程为例,对其施工截流中合龙过程抛投块石料进行了设计研究。考虑龙口应满足通航宽度与吃水深度、合龙施工强度、龙口水流对河床与戗堤裹头的冲刷等要求,拟定龙口的宽度和位置,通过施工截流计算,确定了龙口裹头及合龙各阶段抛投块石料粒径,研究成果可供类似工程参考。Hanjiang River is the largest tributary of the Yangtze River.It has certain characteristics such as wide river channel,large flow,and poor stability of riverbed foundation.A study is carried out on the design of the cast materials used in the river closure process of the Nianpanshan Water Control Project.Considering that the river closure dyke head should fulfill the requirements in navigation width,draft depth,closure construction work intensity,and the erosion of the riverbed and dyke head by the water flow,the width and position of the closure dyke head are proposed.Then,with the closure construction calculation,the particle sizes of the cast materials for each stages of the river closure process are determined.The results could be useful reference for similar projects.
