安全地向前移动

帕丁顿车站（Paddington Station） - 全世界著名的不仅是其创作者Isambard Kingdom Brunel，而且还以一只小型果酱爱熊而闻名。每天平均有26,500名乘客从Paddingtion Station行驶。尽管具有维多利亚时代的优雅和富丽堂皇，但仍制定了计划建造直接在历史地标下方的全新地下车站。这个基础设施项目是由Crossrail进行的，是欧洲最大建筑项目的一部分。新车站将被称为Crossrail Paddington站。

自2011年7月以来，Crossrail制定了计划，以完成伦敦的新地下网络。2011年8月，Costrail Skanska代表Crossrail Limited担任合资企业，被授予Crossrail合同405，以完成该综合体14.8亿英镑的铁路项目。该项目正在建立一条主要的新铁路线，从雷丁和希思罗机场到伦敦西部，再到东部的修道院伍德，延伸了118公里（约73英里）。它也将直接通过伦敦市中心下方。新网络现在将连接七个全新的主线地下电台，所有这些站点都是现有网络铁路服务与伦敦地下之间的重要交互。这些新电台之一是Crossrail Paddington站。

细心的计划以监视上方和下方的结构
直接在伦敦的心脏地带工作有许多挑战。这座城市拥有超过800万人的家园，其地下将处理每年十亿的旅程。帕丁顿的新越野站不仅被现代建筑包围，而且还被历史悠久的建筑所包围。它还位于伦敦市中心密集的区域，其管道，电缆和下水道迷宫，使其成为一个极其复杂的建筑项目。由于伦敦被认为是一个全球城市，因此即使对于一个大规模的项目，它也必须不加干扰。因此，Crossrail站被建造为四层楼高的自上而下结构，在下面的开挖侧面进行时，地面上方有双向实时交通。

With all this digging, loosened dirt in central London could settle unevenly and potentially cause structures to tilt or severe cracking could develop. Constant monitoring of buildings in this area was vital to avoid possible damage and this is how Leica Geosystems products and solutions play an important role in securing the success of this new railway line by monitoring structures and the degree of earth settlement.

Costain-Skanska决定实施实时monitoring solutions by using 52 Leica TM30’s, especially for monitoring designed total stations, and over 1,800 monitoring prisms of all types in and around the Paddington area. The equipment was attached to various key positions on the outside of buildings. Highly accurate 3D data is collected from the total stations that measure key reference points of the various prisms placed strategically throughout the area’s buildings. These measurements, roughly 8,500 points a day, are made in daily cycles. At the recent phase of the project which was called “the bulk dig”, the data capture for the majority of the area’s total stations takes place at six hour intervals each day, after which the data is sent to be processed with Leica GeoMoS, which sends the results to the web portal before they are distributed to the construction team. The use of Leica Geosystems monitoring sensors, software and communications is vital to the Crossrail project, as these accurate measurements provide information on any variations in structures caused by earth movement and minimise risks, not only to the buildings themselves, but also to public safety.

Automated data processing in near real-time
这样的项目需要持续观察,repetitively measuring the same routes and reference points several times daily throughout the entire project’s life span. By using robotic total stations such activities can be done automatically and data is directly transferred for processing using Leica GeoMoS, GeoMos Adjust and GeoOffice software.

三个相互联系的服务器用于在Crossrail施工站点运行Leica Geosystems软件程序。该软件用于检测和分析站点上方和下方的建筑物的地面移动以及建筑物的变形，还有助于加快和简化总站收集的实时数据的处理，最多可达90％亚博5分钟快三可以从现场迅速发行。这个新的Crossrail站的软件解决方案完全来自Leica Geosystems，并且是世界上任何地方的最大类型。据报道
“软件系统必须非常规定和程序，以控制项目的质量和重复性，同时也可以进行环境和施工阶段变化的动态变化。我们的操作不停地运行，我们管理软件系统，以最大程度地减少可能发生的任何故障。这两个软件系统都记录了与惊人的准确性和精确度相关的惊人数据。”

The Leica GeoMoS software solution is a fully automated system for data generation. It offers automated processing and evaluation using statistical analysis, comparing new data to the original base model by using easy to understand graphs. The software also continuously updates deformation analysis and network adjustment with vast volumes of real-time data received by the 44 to 49 * total stations, resulting in highly accurate data delivered fast.

处理数据后，还通过网络调整软件进行了优化，以进行协调的几何形状，地形和准确性。如果任何数据都不在先前收集的数据的±10 mm球体内（通常不年龄在大约六个小时的情况下），则认为这是不正确的。监督操作的工程测量师评估并将数据与预定义的数据参数进行比较，并快速决定是否需要采取措施。

The co-ordination of displaying the processed data with on-site construction teams helps considerably to complete technical work without disruptions. GeoMoS increases not only productivity uptime by displaying real-time data but also simplifies workflows by constantly validating data before issuing it to the teams.

专用的团队和可靠的设备
专门的全天候操作和维护团队积极维护整个Crossrail项目的Leica Geomos软件解决方案，并清洁并维护42至49个总站和1,800多个棱镜。亚博5分钟快三总站需要亚博5分钟快三六人运行，再加上该领域五人的额外兼职人员。所有涉及的总站均在米尔顿·亚博5分钟快三凯恩斯的Leica Geosystems服务中心提供服务和维护。

“Crossrail’s motto is ’Moving London Forward‘. Within our engineering surveying team who run the precise levelling scheme and the largest Leica Geosystems homogeneously adjusted total station scheme in the world, we adopted a complementary motto due to the success we’ve had to ’Moving surveying for monitoring forward’. None of the above however would be possible without the continued support of Leica Geosystems and its supply chain partners”, concludes Steve Thurgood, Engineering Survey Manager for Constain-Skanska Joint Venture.
