桥接大陆鸿沟：监视土耳其地标桥的建设

Authors:ÖzgürAvci＆T/F/D

When finished, the1915Çanakkale Bridge在土耳其将是世界上最长的中跨悬架桥。它将越过4.6公里，它将跨越Çanakkale海峡，并在土耳其和欧洲大陆其他地区之间完成一条新的南部高速公路路线。四家合作伙伴公司正在从土耳其，DAELIM和SK E＆C的合资企业，Limak和YapıMerkezi（DLSY合资公司）（DLSY合资公司）工作。合作伙伴为该项目的每个阶段贡献了全球技术专长和经验。在塔楼建筑阶段，Hwang的挑战是收集有关塔塔的实时定位和长期监控的可靠数据。使用Leica GeoSystems设备，安装Leica的分销伙伴Sistem A.S., Hwang and his team completed the survey works on time, with maximum precision. After the initial construction, the equipment will serve as the permanent monitoring system for the bridge.

国家和国际意义的桥梁

1915年çanakkale桥梁和Malkara-cousakkale高速公路项目是对运输和基础设施的大规模投资，旨在为土耳其的经济做出重大贡献。这条新路线将减轻当前的高速公路连接的压力，该通道通过伊斯坦布尔。这将使商业和旅游旅行变得更加容易，使土耳其更加接近欧洲和巴尔干。除了其实质性的商业重要性外，桥梁的象征意义也受到其一些设计元素的尊重。桥的塔腿之间的2023个元元中跨度象征着土耳其共和国成立的100年。相比之下，海拔318米的塔高度象征着1915年3月18日çanakkale的胜利，Çanakkale胜利是土耳其为争取独立斗争历史上最重要的日期之一。

Accurate positioning data was critical to constructing the towers

笼子（塔楼基础中使用的水密固定结构）的准确定位和塔楼本身对于桥梁的建造至关重要。塔楼的各个部分是异地制造的，设计公差非常紧，因此将结构拼凑在一起时毫米的分数。为了监视构建过程中制造块的实时定位，黄和他的团队使用了16Leica GM30 GNSS接收器用于监视16Leica AS10 GNSS紧凑型GNSS天线, four on each tower.

Each pylon consists of two towers.Leica GNSS Spider software用于计算每个接收器的位置，使用三个单位Leica GR30参考服务器三个Leica AR10 GNSS天线. Hwang explains that they received data in “real-time, 15 minutes, 30 minutes, one hour and two hours baseline processing from the Spider software. TheLeica Geomos监视软件计算基线的平均位置，这些位置是从三个参考文献中计算得出的。收集的数据用于对塔的几何控制，以便在指定的公差内安装塔。”Leica GeoSystems监视解决方案可轻松访问一个方便的位置，可轻松访问所有GNSS单元的所有可用数据，从而帮助该领域的用户及其在办公室中的同事最有效。桥梁制造团队使用实时位置来监视塔的位置和垂直性，以确保将它们安全，准确地插入到位。

Regular reports on weather conditions are crucial in suspension bridge construction

除定位数据外，风速和方向数据以及温度传感器数据还通过Leica Geomos软件吸收。最新的图形和常规报告很快由现在！监视网络服务，节省了Hwang团队的时间：“将实时收集的所有数据组合在一起并立即显示准确的结果！加快了我们在办公室和现场运营的过程。”现在，Leica Geomos！是一个基于Web的应用程序，可通过任何基于Web的设备围绕时钟访问监视项目数据。可以自定义仪表板，以为不同的用户和工作功能（例如工程师或制造团队）提供易于阅读的报告。能够立即访问数据，可以提早检测和解决任何问题。

易于使用的系统在数据收集，处理和培训上节省了时间

After accuracy, the main benefit of the solution to Hwang and his team was the ability to save time and work faster. This included the training, which was a quick process because the Leica Geosystems equipment is intuitive to use. Hwang explains, “We needed to train all the personnel who will be using this solution. It took almost no time to easily adapt to the solution with the help of manuals and training provided by Leica’s authorised dealer SISTEM A.S. During the project they also provided 24/7 on-site and remote support related to any problem faced at the construction site.”

正在进行的监控以确保桥梁乘客安全

“Since the towers have been completed, the product will be used for the cable installation and after the full completion of the project, it will serve as the permanent monitoring system for the whole bridge,” explains Hwang. Leica GNSS Spider was configured to calculate baselines in post-processing mode, and the high-accuracy results are archived in the GeoMoS database, from where periodic reports are generated. Leica GM30 GNSS monitoring receivers, as well as Leica AS10 GNSS antennas, are designed for continuous operations with low energy consumption and are rugged enough for challenging weather conditions – ideal for a bridge at altitude, exposed to the elements. Because installation on large and sensitive structures is difficult and expensive, they are also designed to be future-proof by exceeding the signal needs required today. They will still be in place when the 1915Çanakkale Bridge and Malkara-Çanakkale Motorway is completed in 2022/2023, watching over commuters and travellers for many years to come.
