为实现高速铁路大跨斜拉桥智能化算量,结合当前铁路BIM标准与铁路工程量清单计价指南,给出符合高速铁路大跨斜拉桥BIM计量的工程量清单,基于Revit平台研发了高速铁路大跨斜拉桥工程算量系统。通过分析我国铁路建设工程定额和清单计量规范中所需的计量信息及规则,建立BIM模型构件与工程量清单之间的映射关系,利用Revit二次开发技术并结合SQL Server数据库,对构件的计量信息进行提取与存储,并将计量信息分类汇总,最终实现基于BIM的智能化算量。以高速铁路大跨斜拉桥BIM模型为例对该计量系统进行验证分析,结果表明:本系统可以在确保准确率的前提下提高工程计量的效率,为高速铁路工程量快速统计提供一种新的方法。

In order to realize the intelligent calculation of large-span cable-stayed bridge of high-speed railway,the bill of quantities that meets the BIM measurement requirements for high-speed railway long-span cable-stayed bridges is provided following the current railway BIM standard and the pricing guide of railway bill of quantities,and the research and development of the engineering calculation system of high-speed railway Long-span cable-stayed bridge are completed based on the Revit platform.By analyzing the measurement information and rules required in the norms of China’s railway construction project quota and inventory measurement specification,the mapping relationship between BIM model components and bill of quantities is established,and the secondary development technology of Revit combined with SQL Server database is used to extract and store the measurement information of components,classify and summarize the measurement information,and finally realize the intelligent calculation based on BIM.With reference to the BIM model of high-speed railway long-span cable-stayed bridge,the measurement system is verified and analyzed.The results show that the system can improve the efficiency of engineering measurement on the premise of ensuring accuracy,and provide a new method for the rapid statistics of high-speed railway engineering quantity.
