为研究包边土厚度对分层填筑路堤渗流特征的影响,基于Geostudio-seep软件模拟分析了暂态饱和区及含水率在设置包边土状态下的变化规律。研究表明:通过在分层填筑路堤软土层加设包边土,边坡暂态饱和区区域显著缩小;包边土厚度可依据体积含水率变化趋势和暂态饱和区域范围确定,针对本文分层填筑路堤采用3m包边土厚度即可。
In order to study the influence of the thickness of soil on the seepage characteristics of embankment stratified by stratified filling, the variation regularity of transient saturated zone and moisture content under the condition of setting edge soil is simulated based on Geostudio-seep software. The results show that the area of the transient saturated zone of the embankment is significantly reduced by the addition of the packed soil in the soft soil layer filled with stratified embankments. The thickness of the marginal soil can be determined by the trend of the volumetric moisture content and the transient saturated area. Stratified filling embankment 3m edge thickness of the package can be.
