| 摘 要： | 结合陕西省合阳王村—皇甫庄公路改建工程,分析了黄土高原这一特殊地貌条件下的公路建设中的水土流失现状及形成机理。在详细论述水土流失预估方法和模型的基础上,对黄土高原公路工程建设中土壤侵蚀模数、建设区域内扰动原地貌面积、破坏土地和植被面积、建设区域内破坏水土保持设施面积、新增水土流失量、弃土和弃渣量、施工造成的水土流失危害进行了预估研究,结果表明:①高原公路工程建设中水土流失主要是不利的自然条件(降雨、地面坡度等)与工程开挖、填筑等建设活动互相交织产生的;②弃渣场是高原公路建设中新增水土流失的主要策源地,弃渣场产生的新增水土流失量为3.19×104t,占新增水土流失总量的99.71%;③公路建设造成的水土流失呈线形,影响范围广,应加强施工期的临时防护工程。
