德尔菲法在水利枢纽工程景观桥方案比选中的应用

对于交通系统外的行业，设计人员对其行业特点、要求了解较少，要使设计方案能体现行业特性迅速得到其认可通常比较难。提出利用德尔菲法优选桥梁方案的新方法。以峡江水利枢纽坝顶景观桥为例，聘请15位水利系统的专家，经过两轮征询，在满足功能要求前提下，对桥梁设计方案的结构安全、施工难度、后期管护、工期、造价、景观效果等6项方案优选的权重进行了研究，通过定权求和得到方案的优劣排序。方案比选结果表明：优选出的方案符合业主需要，并兼顾了实际情况，节省了前期设计周期。

Application of Delphi Method in Landscape Bridge Project Selection of Water Conservancy Hub

For designers often find themselves knowing less about characteristics and requirements of industries outside transportation field,it’s difficult for such designs with the relevant industrial features to be accepted eas-ily. This paper proposes a new means of Delphi method in the project selection of landscape bridge project. It takes Xiajiang water conservancy hub landscape bridge project as an example and hires 15 experts from water conservancy system for two rounds of consultation. On the premise of meeting the functional requirements,the six items of project selection including the structural safety of bridge design,construction difficulty,later management,schedule,cost,landscape effect are studied and then the right projects are put in order by weight-ed sum. The results of project selection show that the selected project meets the needs,takes the actual situation into consideration and shortens the early stage of the design cycle as well.
