| Description
| - An open-pit coal mine in the Czech Republic is under reclamation which forms a large lake inside. One side-slope about 40 hectares is still not stable. The slope has two different parts. The upper one with a small inclination consists mainly of %22virgin%22 ground not directly affected by mining. The lower part is a side slope formed by former stripping partly supported by an internal waste dump. A long anchored pile wall has been designed as a support of the upper part of the area. In the lower part a huge stabilisation embankment on the internal waste dump is under construction. The existing monitoring was extended in 2007 in order to prove efficiency of remedial measures. The embankment is instrumented and monitored with respect to its construction phases. Besides the control of the construction process, all gathered monitoring results are used for reverse analyses. A parameter study based on a link of knowledge gained by boring for site instrumentation, CPT applied for installation of BAT pore pressure sensors and pore pressure development including results of 3D deformation monitoring of the waste dump was made. Probable values of shear resistance parameters of the soil on monitored slip surface were determined with the use of the limit state analysis. The study highlighted the effect of pore water pressure distribution to dump stability and another fact that soil parameters are often underestimated to meet monitored instability in calculations. Geotechnical monitoring has been applied for the wall performance control and the efficiency approval of remedial actions. Data gained by long-term high precision monitoring of deformations of two instrumented wall sections together with development of anchor forces are used for back analyses with direct interpretation of piles deflection curves and fitting of calculated deflection curves to measured ones.
