冻融作用下高寒土细沟侵蚀过程与输沙能力经验模型

open access: yesShuitu Baochi Xuebao
目的为探讨冻融作用对细沟侵蚀的影响机制。方法通过室内沟槽冲刷试验,分析不同流量(q)与坡度(S)组合下细沟输沙特征,同时构建输沙能力因子模型。结果1)冻融作用使细沟输沙能力最高可提升34.34%,且影响程度具有明显的坡度和流量依赖性;使临界坡长由未冻融前6.8~8.1 m缩短至5.3~6.4 m。2)冻融前后输沙能力均与流量保持线性关系(Tc=Aq),但与坡度关系发生改变,冻融前随坡度呈指数增长(Tc=-ae(-S/b)+c),冻融后转为幂函数增长(Tc=dSf);建立未冻融输沙能力因子模型为Tc=-0.
