归纳了枢纽互通立交匝道繁多、平面及空间相关关系复杂等特点,通过回顾宁国枢纽互通立交施工图设计过程,说明了根据交通量预测结果,结合地形地貌条件,通过多次调整匝道平纵面指标及相关关系,可以达到缩小互通规模、缩短匝道和桥梁长度、节省占地、节约投资的目的。
歸納瞭樞紐互通立交匝道繁多、平麵及空間相關關繫複雜等特點,通過迴顧寧國樞紐互通立交施工圖設計過程,說明瞭根據交通量預測結果,結閤地形地貌條件,通過多次調整匝道平縱麵指標及相關關繫,可以達到縮小互通規模、縮短匝道和橋樑長度、節省佔地、節約投資的目的。

The paper sums up the hub alternative interchange has many ramps,and its relevant relationships of planes and space are complicated,indicates the combination with the topographical and geomorphologic conditions and several times of adjustment of the horizontal and vertical indexes of the ramps and their relevant relationships can realize the shortening of the interchange scale,reducing the length for the ramps and the bridge lengths,saving the land coverage and investment according to the forecasted results of the traffic volumes by flashbacking the design process for the construction graph for Ningguo hub alternative interchange.
