铜汤高速互通立交设计

铜汤高速公路为山区高速公路，地形、地貌较为复杂，布设互通立交的地形条件十分有限，若采用平原微丘区常用的互通立交型式，会导致大量的高填深挖，对自然环境破坏较大，同时工程造价也会大幅度地增加。故在铜汤高速公路互通立交设计中，设计人员突破设计定式，对每个互通方案都进行了多方案的比选论证，尽可能地让设计作品成为精品，对其他互通立交的设计具有借鉴意义。

Design of Interchange on Tongling-Tangkou Expressway

Tongling-Tangkou expressway is in a mountainous area, where the terrain and physiognomy is complex, so the terrain condition for setting interchange is restricted terribly. If the common forms of interchanges used in plain rolling terrain are applied in mountainous areas, high fill and deep cut will be induced, which will destroy natural environment and increase the cost of engineering greatly. Thereby in designing interchanges of Tongling-Tangkou expressway, designers break through the given form of design to compare and select each project of interchanges, so as to make the design production be a top-quality project. The practice is useful for the design of other interchanges.
