摘要
为分析降雨影响下不同坡度的路堑基床特性,设计室内人工模拟降雨试验和工程背景实地试验,研究降雨影响下不同坡度的路堑基床径流与渗流特性,分析测定路堑基床坡面的入渗量、含水率、流速、产流时间、产流强度、平均水深与坡度的变化规律。分析结果显示:不同坡度同一降雨强度条件下,坡度较大,入渗量、含水率、平均水深较小,产流时间较短,水流速度较快、产流强度较大。
In order to analyze the characteristics of cutting foundation bed with different slopes under the influence of rainfall,design indoor artificial simulation rainfall experiment and engineering background field experiment,study the runoff and seepage characteristics of cutting foundation bed under different slopes of rainfall,and analyze and determine the change rules of seepage volume,water content,flow rate,production time,production intensity,and average water depth and slope.The analysis results show that different slopes under the same rainfall intensity,large slope,small infiltration volume,water content,average water depth,short yield time,fast flow velocity and large yield intensity.
