摘　　要：　本文用当地32 5普通硅酸盐水泥掺Ⅰ级粉煤灰与优质外加剂配制的大流动度高性能混凝土,不仅解决了该工程的抗硫酸盐侵蚀与抗冻、抗渗等耐久性,而且为工程节约资金数千万元;用当地42 5硅酸盐水泥与硅粉、粉煤灰并掺入膨胀剂、高效减水剂配制的大流动度、高强、高密实性、微膨胀补偿收缩混凝土,对减少混凝土裂缝与抗冲磨提供了优质配合比。2000年已竣工的527m导流洞与正在浇筑的300m冲砂洞仅发现二条长3m左右的微细裂缝;底板抗磨层C60高强混凝土仅发现若干条微细裂缝,但未发现一条有害裂缝,说明本工程所采用的混凝土配合比与施工技术都是成功的。In this article,we using P.O32.5 cement in the locality,high quality fly ash and concrete admixture produced HPC,not only resolved corrosion by sulphate and durability in concrete of this project,but also saved a lot of fund for the project.Meanwhile,we researched that the high performance compensate the constringencies concrete produced with PO425 cement,silica fume,fly ash and added expansive agent and efficient water reducer,not only reduced crevice of concrete,but also improved abrasionresistant of concrete.We didn't found any harmful crevice in completed 300m long tunnel.
