改性PP纤维混凝土在季节冻土区渠道衬砌中的应用

The application of the Modified PP fiber reinforced concrete in the channel liningof the seasonally frozen area

吉林省是最早在渠道防渗工程中使用改性PP纤维混凝土技术的省份,在渠道防渗衬砌工程中取得了较好的社会效益和经济效益。但在应用的同时,也存在着盲目使用及使用不当等问题。因此,应科学认识和客观评价改性PP纤维混凝土的性能,并重视后评价工作。

Jilin Province is the first one using the modified PP fiber reinforced concrete technology in channel lining against seepage,and achieved good social and economic benefits.In the same time,there are improper use and other issues.Therefore,we should objectively evaluate and scientific understand the performance of modified PP fiber reinforced concrete,and the importance of post-evaluation.
