摘　　要：澳门地区完善新口岸区污水截流管隧道工程,为国内首例成功应用无筋钢纤维混凝土管片项目。本次研究依托本项目,通过对无筋钢纤维混凝土管片设计中分块及荷载选择、计算模型及公式选取,结合有限元结构计算软件分析,通过基础力学试验验证,合理确定设计参数,提供一套完整的设计方法。Macao region has improved the sewage interception pipe tunnel project in the new port area,which is the first successful application of non reinforced steel fiber reinforced concrete pipe segments in China.This study is based on this project,and through the selection of blocks and loads,calculation models and formulas in the design of unreinforced steel fiber reinforced concrete pipe segments,combined with finite element structural calculation software analysis,verified through basic mechanical tests,reasonably determined design parameters,and provided a complete design method.
