摘要：城际轨道交通跨湖段高架桥梁下部建筑施工需搭建水中作业平台，多采用钢栈桥形式，现行城市轨道交通定额体系及市政定额体系中没有相关定额满足其计价需要。以南京至高淳城际轨道交通禄口新城南站至高淳段工程为例，阐述水中作业平台计价方法，并介绍技术经济指标及影响造价的主要因素，为后续类似项目提供参考。

Abstract：The construction of the lower part of the viaduct cross-lake section of intercity rail transit needs to build operating platform in the water，and usually uses steel trestle form，there is no relevant quota in the existing urban rail transit quota system and municipal quota system to meet its pricing needs. Taking Nanjing - Gaochun intercity rail transit from Lukouxincheng south station to Gaochun section as an example，this paper expounds the pricing method of operating platform in the water，introduces the technical and economic indicators and the main factors affecting the cost，in order to provide references for the follow-up projects.
Keywords：intercity rail transit；operating platform in the water；steel trestle；engineering cost
