摘　　要：以武汉临空大道与机场二高速为例,研究了新建公路与既有高速公路的互通方案,重点研究了互通工程中匝道线路方案比选、路面横断面布置、路基填方工程、路基防护、不良地质地段及特殊路基设计、新旧路面结构拼接设计、桥梁方案设计和桥面铺装工程等,对同类互通工程建设方案比选具有参考意义。Wuhan Linkong Road and Airport Second Expressway was taken as an example to study the interconnection plane between the newly built road and the existing expressway project.The focus was on the comparison and selection of ramp route schemes,pavement cross-section layout,roadbed filling engineering,roadbed protection,unfavorable geological sections and special roadbed design,new and old pavement structure splicing design,bridge scheme design,and bridge deck pavement engineering in the interconnection project.The results have reference significance for the comparison and selection of similar interconnection engineering construction schemes.
