摘　　要：玻利维亚ICLA水电站工程主要任务是发电,同时兼顾灌溉。水库库容15.2亿m^3,其中有效库容8.6亿m^3。坝址多年平均径流量为16.7亿m^3,多年平均悬移质输沙量为3352万t,推移质输沙量369万t,总输沙量3721万t。多年平均悬移质含沙量为21.0 kg/m^3。库沙比约50,工程泥沙问题十分突出,通过水库泥沙数学模型研究,提出合理的水库泥沙调度运行方式,以最大限度地延长水库寿命,发挥工程效益。The main task of ICLA hydropower project is power generation,while taking irrigation into account.The reservoir storage capacity is 1.52 billion m^3 in which the effective storage is 860 million m^3.The average annual runoff at dam site is 1.67 billion m^3,average annual sediment discharge of suspended load is 33.52 million tons,and of bed load is 3.69 million tons,the total sediment discharge is 37.21 million tons.Sediment concentration of average annual suspended load is 21.0 kg/m^3,with reservoir sediment ratio of about 50,the sediment problem is very prominent,the purpose of sediment research is to put forward reasonable regulation and operation mode of reservoir sediment via mathematical model study of sediment so as to maximize the life of the reservoir and promote the benefits of project.
