Challenges: Current slope monitoring exercises are carried out manually. Several methods are being used to monitor slope movements. Some of the most common methods are satellite imageries and conventional Global Positioning System (GPS) which require manual observations. Others prefer to use 3D laser scanners that can scan any topography and provide quick assessments of the slope. Though these methods are efficient in monitoring slope movements, they lack realtime monitoring and predictive analytics of when landslides will happen.
Realtime slope monitoring is still not good enough to prevent the loss of lives and assets during a landslide. Predictive monitoring and an early-warning solution is essential to save lives.
Current slope monitoring is carried out manually and lack realtime and predictive analytics.
Solution: To help tackle the issue of slope management and monitoring, Pembinaan TMC Sistem has taken the leap into Big Data and Analytics and has come up with a revolutionary solution. They developed a remote landslide sensing system with Predictive Monitoring and Early Warning Solution known as Integrated Deformation Early-warning Alert Solution (IDeas). This new system is a huge improvement over the traditional, labour-intensive and costly methods of slope monitoring.
IDeas uses mapping, 3-D scanning and smart sensing—all combined together to create one cohesive ecosystem that is able to analyse and predict slope movements, thus preventing landslides. This state-of-the-art integrated solution runs on a cloud platform, allowing the company to easily scale their resources, making the system flexible and cost-effective.
On site, a robotic station automatically tracks and measures the position of all fixed prisms at a defined interval.
The concept being used is to measure the displacement of prisms fixed on selected critical points on the slope or monitored structure. Then, the position (x.y,z) will be surveyed to produced a set of reference points for displacement calculation. Theoretically, if there is no movement, the position of the prisms will never change. If there are any differences in the measured positions, it can be interpreted that there is soil movement or worse, a landslide. The measurements will not only indicate the size of displacement, but the direction of soil movement as well.
If the displacement value is bigger than the acceptable defined tolerance, it will trigger an alarm and send out warnings to respective personnels via SMS, email and social media. Realtime monitoring might warn you when a movement is detected; sometimes, however, by the time movements are detected, it could be too late. IDeas tries to forecast the incident as precisely as possible before a landslide actually happens.
Accelerated soil erosion is detected 3 months before slope failure. By analysing realtime data, IDeas can tell if a slope failure will happen. Predictive analytics can be used on historical data to forecast when a slope failure will happen.
TMC IDeas integrates high-precision land surveying instrument with realtime communications to monitor any environment 24 hours a day, seven days a week.
Benefits: IDeas has been used in a Malaysian gold mine, one of TMC’s target industries. As safety is paramount in the mining industry, serious damages or life lost due to landslides will lead to the mine being shut down for investigations. With IDeas, the gold mine in Malaysia minimized their risk of a landslide which could potentially cost them US$1.5 million for every week its operations are disrupted..
