Research on Key Technologies of BIM and GIS in Saudi Arabia NEOM Tunnel Project

利用数字仿真模拟方法,在保障施工安全的基础上优化爆破方案。提出了大断面隧道大孔距设计的理论方法,有效控制隧道断面和保留岩体的损伤,并降低成本。通过模拟二维、三维路线的联动,可以对比剖切地质体,按里程桩号实时查询地质体产状及地质风险信息,根据围岩等级对施工方案进行分析,辅助施工决策。通过将项目的BIM模型接入GIS数据平台,可以将地质超前预报的信息与项目进度进行动态关联。采用BIM4D进度管理手段,采用BIM技术和数字化手段管理项目的计划和进度,帮助项目在高质量的基础上合理压缩工期,达到降本增效的目的。

Using the digital simulation method,the blasting scheme is optimized on the basis of ensuring construction safety.The theoretical method of large hole distance design for large section tunnels,which can effectively control the tunnel section,retain the damage of rock mass,and reduce the cost,is put forward.By simulating the linkage of two-dimensional and three-dimensional routes,the geological bodies can be compared and cut,and the geological body occurrence and geological risk information can be queried in real time according to the mileage pile number.The construction scheme was analyzed according to the surrounding rock grade to assist the construction decision.By connecting the BIM model of the project to the GIS data platform,the information about geological advanced prediction can be dynamically correlated with the project progress.The application of the BIM4D schedule management method,BIM technology and digital means for the management of project plans and schedules can reasonably compress the construction period on the basis of high quality and achieve the purpose of reducing cost and increasing efficiency in the project.
