摘　　要：以太旧高速公路桑掌至坡头段为研究对象,结合既有道路指标、构造物的分布及使用情况、周边采空区影响、河道防洪、村庄及文物分布等,统筹考虑行车安全性和旧路利用率等因素布设多个改扩建方案进行综合对比论证,合理确定改扩建方案,对山区高速公路复杂路段改扩建方案的选择具有一定指导意义。Based on the Sangzhang to Potou section in Taijiu Expressway,combined with the existing road indexes,the distribution and utilization of structures,influences of surrounding mined-out areas,river flood control,and distribution of villages and heritage,considering the driving safety and utilization rate of old roads,this paper designed multiple reconstruction and expansion schemes for a comprehensive comparison and demonstration,and rationally determined the final scheme.This paper has a certain guiding significance for selecting the reconstruction and expansion scheme of complex road sections in mountainous expressways.
