【摘要】：針對無紡布淤堵指標(biāo)的評價問題,通過對航道整治工程岸坡反濾層中常用的短纖針刺非織造土工布的淤堵指標(biāo)的透水準(zhǔn)則和梯度比準(zhǔn)則進(jìn)行研究,找出兩者之間的關(guān)系結(jié)合點:標(biāo)準(zhǔn)排水邊坡的水力梯度值和梯度比限值,并基于此結(jié)合點開展無紡布的淤堵試驗,對淤堵指標(biāo)的評價模型進(jìn)行探索研究,擬合出航道整治工程岸坡反濾層中無紡布淤堵指標(biāo)的評價模型公式,以期指導(dǎo)計算無紡布能正常發(fā)揮反濾功能的時間期限。成果填補(bǔ)了該領(lǐng)域研究的空白,奠定了該領(lǐng)域研究的基礎(chǔ),為今后促進(jìn)該領(lǐng)域的研究具有重要的價值和意義。
[Abstract]:Aiming at the problem of evaluation index by non-woven clogging, the waterway engineering slope filter used in fiber needle punched geotextile clogging index criterion and gradient ratio criterion of pervious research, finds the relationship between the two binding sites: water stress gradient standard drainage slope value and gradient ratio, and based on this point to carry out the combination of non-woven clogging test, studies the evaluation index of clogging model, the fitting formula evaluation model of Waterway Engineering Slope in the non-woven filter layer clogging indicators, calculation in order to guide the normal functioning of non-woven filter. The time limit results to fill the blank of the research in this field, laid the foundation of the research, it has important value and significance for the future promotion of the research in this field.
