Remedial Works on the Smrečje Landslide, Croatia

The Smrečje Landslide was occurred on the county road near the Gerovo village in Gorski Kotar region, Croatia, before more than 10 years. The landslide location is forming in clastic formations of shale, sandstone and marl rock masses from Triassic age. The landslide was overtaken 100 m long part of the road construction. The instability was evidenced in long term creep process with deformation increments associated with the seasonal water content variations in the clayey superficial deposit. Deformations on the pavement construction were reaching unacceptable values during 2008 that caused necessity of complete landslide remediation. Field investigations were executed and the remediation measures were designed. Field investigations were included investigation drilling, soil and rock mass samples taken, geophysical measurements using seismic refraction and geoelectrical tomography techniques so as engineering geological surface mapping. In the paper we will present description of the Smrečje landslide, results of the conducted field investigations, so as designed remediation measures. Based on the remediation design, the remediation works were constructed in the spring 2009.
