Combining geotechnical and geodetic data for monitoring

作者：Renata BarradasGutiérrez

Cities are evolving entities that need to adapt to accommodate the needs of the people, sustain economic functions and provide well-being and life quality. Adapting and building new infrastructure in cities with rich cultural heritage and city Old Towns pose a greater challenge as any construction works must maintain the integrity of historic structures.

包括历史结构在内的关键监测正在世界各地发生，而我们大多数人都没有注意到。海德堡就是这种情况，在其旧城区的核心中，正在监视1871年左右建造的历史悠久的隔离墙。为了应付可容纳汽车的需求，正在建造一个地下停车场，就在历史悠久的挡土墙和地基旁边。挖掘所需的构造10米深的坑被无聊的桩加固in front of the historic retaining wall reinforced with anchors.

For this German city situated on the Neckar river, this retaining wall is important beyond its historic value – the structure restrains soil to stabilise a slope. Toensure its reinforcement works are stable, securing measures are adequate and the historic wall is preserved, monitoring is required.

将新建筑集成到现有的旧结构中

TPI Vermessungsgesellschaft mbH (TPI)是一家在德国莱茵 - 梅因地区进行测量和地理信息的工程公司maintain its integrity。

“我们将扮演part in preventing damage as long as any damage can be detected and technically measured in a timely manner,”said Dipl.-Ing. Dietmar Keiser, project manager at TPI.

To detect any tilts on the wall, capture any displacements in 3D and detect any settlement on the wall, TPI’s tailor-made monitoring solution includes:

• 一个Leica Geosystems Total Station TCRP 1201
• GeoMoS Monitor
• GeoMoS Now!
• 13 Leica GPR112 prisms
• Eight wireless inclinometers with two-axis
• One meteo sensor

The 3^rd方面

设置了两种不同的监视方法以保证独立检查。棱镜监控以大地重点3D变形允许检测任何横向运动或墙壁沉降。一个总站连续测量五个参考和八个监视点。有了岩土技术的焦点，两轴倾斜仪为检测墙倾斜s。Sensors are connected in a self-forming mesh network where each node can act as a data sender and receiver. This guarantees the measured data will reach the gateway in the fastest possible way, from where it will be uploaded to the cloud and automatically processed byGeoMoS monitoring solution。

All measured data, including data from the tilt sensors, angle and distance measurements to prisms and environmental data, such as temperature and air pressure, was自动收集和分析地球物。所有获得和处理的数据都报告在墙上没有倾斜，因此，增援部队良好且稳定，团队可以进行施工。

“ Geomos Monitor和Geomos现在！是真正复杂的产品，肯定会在特定领域进一步开发。bob综合app下载得益于我们在Leica Geosystems的联系的可靠支持，系统的设置非常简单。该程序的用户指南也非常好。即使在大约五个月后，我仍然会收到有关单个程序功能的技巧和支持。”Keizer在TPI说。

TPI工程师和测量师过去使用的Leica Geosystems总站，GNSS，Levels，激光扫描仪和激光跟踪器设备。这次量身定制的监控系统为专家提供了confidence to dig and build underground。Rounded by competent support by Leica Geosystems staff, the secure could storage and web service enables TPI experts to:

• Permanently and automatically measure without manual intervention
• Automatically evaluate and trigger a message when the limit is exceeded
• Continuously monitor the results via the internet
• Enable designed stakeholders, such as their customer, access results.

确保所有人和一切安全

城市地区的发掘对周围环境的人们，结构和建筑物构成风险。全面和可靠的监控系统对于measure any deviations and make better-informed and timely decisions and mitigate any risks。

Supported by Leica Geosystems’ specialists, TPI setdifferent monitoring methods with a solid reference frame其中包括其他参考点，保证独立检查。With the confidence to detect any movement to the millimetre, experts can upgrade an urban area while preserving its cultural heritage.
