线形设计中用来填挖平衡的方法

Method of balancing filling and excavating in linear design

指出公路线形设计除满足相关设计标准和规范外,还应同时考虑经济、人文等因素,通过引入加权地面线,使路面设计标高与加权地面标高相符合,从而使填挖平衡且保证工程量最小。

It points out that linear highway design should consider economic and humanistic factors besides satisfying relative standard and rules. Through the introduction of weighted ground line, road surface design elevation is equal to weighted ground elevation so the filling and excavating is balanced and takes the minimal labor.
