| 摘 要： | 目前丙凝灌浆帷幕耐久性的定量研究成果较少，且缺乏较完善的公认分析方法。分析了丙凝灌浆帷幕耐久性的研究现状，提出了丙凝灌浆帷幕抗挤出能力和丙凝胶体老化性能研究的思路和方法，并结合丹江口水利枢纽工程坝基丙凝灌浆帷幕耐久性的研究，定量推求了丙凝胶体分子结构的耐久性寿命。分析表明，在幕体抗挤出能力良好的条件下，丙凝灌浆帷幕耐久性寿命是有保证的。

| Abstract: | The research achievement in the quantitative study of durability of acrylamide grouting curtain is rare and the perfect and general accepted analyzing method is needed.The research situation of durability of acrylamide curtain is studied.The thought and method of studying the extrusion resistance capability of acrylamide grouting curtain and aging property of acrylamide colloid are proposed systematically.Combining with the study of durability of acrylamide grouting curtain of dam foundation at Danjiangkou Hydro-complex,the durability life of acrylamide gel molecules is obtained quantitatively.The results show that in the case of high extrusion resistance capability,the durability life of acrylamide grouting curtain can be guaranteed. |
