考虑土的性质的“加权地面线法”是通过优化道路土方量,实现工程总费用最小化的有效方法,这种方法要求纵坡设计线尽可能接近加权地面线,同时充分考虑土的性质,从而实现填挖平衡和土方量最小化,进而达到减少工程总费用的目的。 The Weighted Ground Line Method, which takes into account the nature of soil, is an effective way to minimize the total cost of the project by optimizing the amount of earthwork on the road. This method requires that the design line of the longitudinal slope should be as close as possible to the weighted ground line, taking full account of the nature of the soil, In order to achieve filling and excavation balance and earthwork minimization, thus reducing the total cost of the project.
