摘　　要：选线应充分考虑公路线形、公路结构、环境保护和景观开发等因素,合理选点布线,尽量减少破坏植被;尽量避开不稳定地带,尽可能做到填切平衡,合理安排,减少取、弃土量,加强生态防护、排水和植被返绿工程。综合考虑项目所在区域地形、地貌、通道分离立交设置情况,以及河流设计水位以及地下水位、路基填料情况、排水系统等因素确定路基最小填土高度,并采用合适的路基高度,有利于将风吹雪害降到最低程度。Route selection takes fully into account the factors of highway alignment,highway structure,environmental protection and landscape development,so as to reasonably select points and routing,minimize damage and non-destruction,avoid unstable areas as far as possible,make filling and cutting balance as far as possible,and arrange reasonably.Reduce the amount of waste soil,strengthen ecological protection,drainage and vegetation green project.The minimum fill height of subgrade is determined by taking into account such factors as topography,geomorphology,channel separation interchange,river design water level and groundwater level,subgrade filling condition,drainage system and so on.The suitable height of roadbed will help to minimize the damage caused by wind and snow.
