摘　　要：通过对科特迪瓦波波里项目的天然沙、筛分半成品料进行颗分试验,在设计出最佳的掺配比例后再对筛分系统进行改造,实现了天然沙与筛分半成品料的自动掺配,进而实现了高效率、低成本的大坝反滤料生产,满足了渗透性(D_(15))、稳定性(D_(15)/d_(15))的设计指标。阐述了对筛分半成品料与天然沙掺配组成的大坝反滤料的设计情况。Through the particle size test of natural sand and screened semi-finished materials in the Popoli Project in C o^te d′Ivoire,the screening system was modified after the optimal blending ratio was designed,and the automatic blending of natural sand and screened semi-finished materials was realized,thereby realizing the high-efficiency and low-cost production of dam filter materials,meeting the design indicators of permeability(D15)and stability(D _(15)/d _(15)).The paper decribes the design of the dam filter material composed of screened semi-finished materials and natural sand..
