监视a landslide recovery operation

The benefit of combining technologies; the detection speed of radar and the reliability of interpretation of movements via measurements from total stations.

On 6 February 2020 at a landfill in Zaldibar, northern Spain, thousands of cubic metres of waste collapsed. Tragically, the collapse killed two employees of the refuse company responsible for the site. The landslide spread beyond the landfill and onto a highway, the busy AP-8 which runs from east to west across Basque Country. Interbiak, the public company in charge of managing the highway, immediately instructed engineering partnerInfoTOP设置一个系统以监视折叠材料。Infotop安装了一个配置的Leica GeoSystems自动化监控系统，该系统配置为任何进一步的运动或不稳定的工程师，并通过他们，救援团队和紧急服务。

增加安全稳定landslide

The landslide dragged thousands of cubic meters of material – some toxic and flammable - from the landfill which occupied an area 30 metres wide and about four metres high. Emergency services needed to quickly control the stability of the slopes in order to begin rescue operations. Working in a precarious and unstable situation, they needed an alert system to warn them should the waste material move again.

It was a challenging installation. Because of the site's hazards, InfoTOP's monitoring system needed to be entirely remote, without any manual measurement. It could only be installed within 400 – 800 metres of the landslide, and more crucially, had to run 24/7 without any operators. In terms of speed, the data collected by the system needed to be processed automatically, with reports generated and sent to InfoTOP's geology partnerIngek用于解释。对于与分布式团队的协调，必须可以从任何地方访问数据。最后，需要配置监视系统以通过短信和电子邮件实时向技术人员发送警报。

Two monitoring systems for a complete picture

Faced with these conditions, InfoTOP set up an automated monitoring solution combining total stations with radar. They installed twoLeica Nova TS60亚博5分钟快三由移动通信提供的总站Leica ComGate10通过虚拟专用网络（VPN）使用4G技术的路由器。总站使用亚博5分钟快三该区域中安装的100多个棱镜进行了测量。安装在混凝土支柱上，将一个总站放置在雷达旁边，第二个站位于垃圾填埋场附近的区域中，以测量第一个车站看不到的棱镜。然后由Leica Geomos软件安装在虚拟云基础架构上。

另外，IDS HYDRA-G– remote sensing monitoring system based on radar technology – was installed to give a continuous measurement sweep. With 120 degrees of coverage horizontally and 30 degrees vertically, this covered most of the danger zone, except for areas hidden by vegetation. Designed for early warning and real-time measurements of sub-millimetric displacements in cut-slopes, the HYDRA-G provided real-time data of movements, transmitted to theIDS监护人software for interpretation and alarm management.

为什么两个系统组合在一起？速度，可靠性和数据深度

雷达系统允许通过在较大距离范围内的干涉测量法（波的干扰）进行连续测量，从而在秒内识别运动，从而检测到800m的±0.1mm。尽管高度敏感，但它只能在视线内监视。并非所有滑坡的区域都允许雷达测量，这是由于其倾斜度和植被隐藏的部分。因此，多个总站覆盖了雷达覆盖范围和阴影区亚博5分钟快三域中的任何盲点和测量的棱镜。PRISM数据帮助工程师和地质学家了解了每个区域的真实运动，并确切地了解了发生的3D运动。这些高度互补的技术提供了雷达检测的速度结合，并通过总站测量来提供有关运动的可靠空间信息。Leica Geosystems和IDS Georadar技术和软件形成Hexagon GeoSystems的监视解决方案。亚搏苹果app

连接和即时警报

Leica Geomos和IDS Guardian数据处理软件允许Infotop自动化系统，以便可以在Ingek上与专家立即与专家共享数据以进行解释。GeoMoS Now!is an easy to use web interface that made it possible for the geologists to analyse the situation from any location, 24/7. The system was also configured with a series of real-time alerts that sent warnings immediately if the configured thresholds were exceeded.

Safety in the immediate aftermath and throughout the phased disaster recovery process

谈到监测系统时，Infotop的Oskar Moral说：“如果发生任何动作，它使我们能够预警，以确保员工的安全以及对稳定的控制。automated without the need for operator intervention to control the equipment day-to-day; this has allowed us to obtain immediate results without further processing. We have not found another solution that matches the advantages offered by the Hexagon Geosystems’ monitoring system."

“此外，这是一个可扩展的系统，它使我们能够在这个困难的项目不断发展时管理传感器。”
