平原微丘区低路堤高速公路平面规划设计探讨

低路堤高速公路在平面规划设计方面有很多与常规高速公路方案不同的地方。在初步拟定线形时，应该考虑与原有道路的相互协调，可以在确定线形以后通过合并支线、拆除支线和修改支线的方法使得地方路网配合低路堤高速公路。另外，为了尽可能地减少横向穿越公路的需要，减轻公路的负担，可以通过对公路两旁产业结构的调整，或者对行政区进行重新规划改革，将横穿的需求降到最低。

Study on Horizontal Layout Plan and Design Methods for the Low Filled Embankment Expressway in Plain and Slight Foothill Area

There are many difference between the horizontal layout plan and design and general highway design program. In initial alignment design, we should consider the coordination to original road. After confirming the alignment, amalgamating branch road, abolishing the branch or modifying the branch could make the local highway net assort with the freeway. In addition by adjusting the industry structure along the freeway or re-planning administrative layout the traversing demand could be minimized.
