SLOPE STABILITY ANALYSES

Mężczyzna dokonujący analizy stateczności na laptopieOur offer also includes conducting stability analysis of the soil in landslides, natural and artificial slopes, as well as railway and road embankments. 

 

COMPUTATION METHODS

We conduct the computations based on cross-sections interpreted by our specialists using data from field and laboratory tests. We apply numerous methods, including Bishop’s and Fellenius’s, which are some of the most commonly used analytical methods of stability computations in Poland and Europe. Our stability analyses take into account the provisions of the Regulation of the Ministry of Transport and Economy on the technical conditions to be fulfilled by public roads and their location – Dz.U. of 14 May 1999 – Section 2 - § 144 “stability indices of escarpments and slopes, determined individually through methods stipulated in Polish Standards, shall not be lower than 1.5”. If it is necessary to relate the results to other standards or guidelines, we select appropriate computation factors, so that they comply with the assumptions.

 

COMPUTATION DATA

One of the most important elements in stability computations is entering input data, namely, soil parameters. We strive to map geotechnical parameters as accurately as possible, which is why we do not apply correlations available in standards and source literature – instead, all data used to develop a computation model is determined with direct methods based on soundings, as well as laboratory testing on sampled soil. The high quality of CPT-u soundings we conduct, enables continuous determination of the physicomechanical parameters within a profile, verified by laboratory tests.
