盘锦枢纽互通立交改扩建设计方案探讨

Discussion on Reconstruction and Extension Scheme of Panjin Hinge Interchange

盘锦枢纽互通立交是连接京沈(北京至沈阳)高速公路、盘海(盘锦至海城)高速公路的三路枢纽互通式立体交叉,拟建的阜盘(阜新至盘锦)高速公路与盘海高速公路对接、与京沈高速实现互通,因此需将原三路枢纽互通改扩建为四路枢纽互通;就该枢纽互通方案研究阶段的设计思路、互通的功能和形式作简单介绍和分析比较,来探索复杂因素控制条件下三路枢纽互通改造为四路枢纽互通的设计思路和选型问题。

Panjin hinge interchange is the three-road hinge interchange connecting Jingshen Expressway（from Beijing to Shenyang） with Panhai Expressway（from Panjin to Haicheng）.The planned Fupan Expressway（from Fuxin to Panjin） will be docking with Panhai Expressway and Jingshen Expressway,and therefore,the original three-road hinge interchange should be reconstructed and extended to four-road hinge interchange;the design idea and type selection of transferring three-road hinge interchange to four-road hinge interchange under the conditions controlled by complex factors are discussed through the introduction and comparison of design idea,interchange functions and forms at the study stage of hinge interchange.
