摘　　要：沙迦桥(前身为多哈湾大桥)总体规划是应多哈市政规划部(MMUP)的要求由圣地亚哥·卡拉特拉瓦建筑事务所设计的,其特点是高效的土木工程方案和极具标志性的设计的独特结合。总体规划以连接机场区、西湾金融区和文化城的主要交通枢纽为特色。圣地亚哥·卡拉特拉瓦取代了之前仅限隧道系统的提议,提出一种新的解决方案——在隧道系统三端各建一座桥梁。桥梁与之前提出的交通系统的连接在所有三个位置都遵循相同的原则——条短隧道在沿海地区下方穿过,使桥梁在下降到海底连接回主公路隧道之前能够在海上出现。The Sharp Crossing(formerly Doha Bay Crossing)Masterplan has been developed by Santiago Calatrava at the request of the Ministry of Municipal Affairs and Urban Planning(MMUP)and features a unique combination of an efficient civil engineering solution and a highly iconic design.The masterplan features a major traffic connection linking the Airport Area with the West Bay Financial District and the Cultural City.Substituting the formerly proposed tunnel-only system,'Santiago Calatrava has designed a solution with a bridge at each of the three ends of the tunnel system.The connection of the bridges to the previously proposed traffic.system follows the same principle at all three,locations-a short tunnel underpass runs below the coastal district allowing the bridges to emerge offshore before descending beneath the sea to connect back to the main road tunnel.In this way,each bridge reads as an individual sculptural piece with distinct character drawing on the constraints of the adjacent,urban environment.
