Abstract爲探讨高速公路施工期不同人工地貌水土流失规律,对西昌-攀枝花高速公路不同下垫面边坡 进行了天然降雨条件下水土流失观测试验,结果表明:(1)不同人工地貌边坡的主要侵蚀形式是沟蚀.(2)路堤边坡主要侵蚀因数是次半宽雨量和平均雨强,土 壤侵蚀量与次半宽雨量及平均雨强的相关关系分别爲:0.9985-0.9989及0.9357-0.9515.(3)路堑边坡主要侵蚀因数是次汇水面宽雨 量及平均雨强,土壤侵蚀量与次汇水面宽雨量及平均雨强的相关关系分别爲:0.9967-0.9998及0.9405-0.9551.(4)弃土场边坡主要 侵蚀因数是次平台雨量及平均雨强,土壤侵蚀量与次平台雨量及平均雨强的相关关系分别爲:0.9997及0.9552.
Other AbstractIn order to investigate the behavior ofsoil erosion on the slope ofthe different underlaying surface
during construction.the experiment with natural rainfall on Xi chang·Pan zhihua highway was conducted,The results show that:(1)the main typc of soil erosion is gully erosion,the amount ofsoil erosion caused by gully erosion is
higher than that by surface erosion.(2)nc principal factor causing soil erosion on the slope ofthe embankment is
individonl日ffflount of precipitation。the width of 11ln embankment and rain intensity.There are well linear
relationships bctweeg the amount ofsoil exosion and the principal factor,and their correlation coe伍cient are 0.9985
-0.9989 and0.9357--0.9515.(3)Theprincipalfactorcausing soil erosiononthe cutting slopeisindividual amount
of precipitation,the width of the cutting slolⅪand rain intensity.There ara well linear relmionships between the
amount of solI erosion and the p—ncival factor,and thcir corrclation coefficicnt are 0.9967·0.9998 and 0.9405—
0.9551.(4)The principal factor causing soil erosion 0n the slope ofthe dumped soil arca is individual amount of
precipitation,the width ofthe flat roofand rain intensity.There arc well linear relationships between the amount of
soil erosion and the principal factor。and their correlation coefncient are 0.9997 and 0.9552.
