碎石聚氨酯护坡应用的初步研究
首发时间:2008-02-19
摘要:碎石聚氨酯护坡是一种新开发的水利技术。其结构与碎石沥青护坡相似,不同的是碎石以聚氨酯粘合而不是沥青。为了研究碎石聚氨酯护坡在实际应用中的可行性,对碎石聚氨酯护坡和碎石沥青护坡进行了以实验为主的比较研究;进行了标准四点弯曲扫描频率实验、标准单调三点弯曲强度实验、孔隙率实验、坡上稳定性实验、波浪爬高实验、界面渗透率实验、相对抗磨损能力实验和一些在计算机堤坝安全评估分析程序GOLFKLAP中进行的计算。研究结果表明碎石聚氨酯护坡在实践中的应用是可行的。

PRELIMINARY STUDY OF PUR-REVETMENT扴 APPLICATION
Abstract:PUR-revetment is a newly developed method for hydraulic application. Its structure is similar to that of open stone asphalt revetment, but the crushed stones are glued by polyurethane (PUR) instead of bitumen. To study the feasibility of applying PUR-revetment, a research based on the comparisons between PUR-revet琺ent and open stone asphalt revetment was carried out, for which, a standard four-point bending frequency sweep test, a standard monotonic three-point bending strength test, a porosity test, a stability on slope test, a wave run-up test, an interface permeability test, a relative resistance to abrasive action test and some cal琧ulations in GOLFKLAP were done. It suggests PUR-revetment is applicable in practice.
Keywords: PUR-revetment, PUR-stone, polyurethane, open stone asphalt revetment, bank protection
