GINTEC conducted a national dam-break simulation experiment utilizing the new GINTEC Array Displacement Meter ADM deformation monitor system.
The purpose of the experiment was to simulate an earth dam breaching following impound water overload and derive deformation and force conditions using the GINTEC system. Click the video in the Media section below to watch footage from the experimental procedure.
A 5-meter array displacement ADM (0.5 meters/segment) was installed in 2 boreholes within the dam's body. Each borehole was 5 meters in depth. The dam was then gradually filled with water and the monitor system recorded the deformation which slowly increased.
At a certain point, the recorded deformation was more than 1 centimeter, a value that shows potential instability of the earth structure.
As water flow was kept constant, the dam started to destabilize. It then started failing when the filling water exceeded the structure's body load.
The deformation value at the moment of breaching is the highest recorded through the experiment (1,62 centimeters). After the failure of the dam, water flows freely out of the structure, therefore the accumulated water in the dam is reduced. Consequently, the loads applied and the accumulated deformation started to decrease.
The collected monitoring data precisely reflected the changing deformation of the dam throughout the experiment. The results are recorded and assessed in real time. The ADM deformation monitor system proved to be efficient in precise intelligent monitoring projects.
