Stability problems of a dam with cracks in Wengfu, China
Description: A dam for storage of phosphorus gypsum stack showed stability problems with cracks along and close to the main dam. The entire area investigated was approx. 116.000 m².
The main targets of our investigation included
- a leak detection of the integrity of the Ditch Liner and
- a structural inside view into the main dam and slope to investigate cracks, sinkholes and deep underground stability problems
Texplor conducted a comprehensive survey with geophysical technologies (Gravimetry, ERT). The results showed a detailed tectonically picture of what happened in the limestone subsurface of the dam and detected major tectonic fault zones.
