Investigation of landslide in complex geological conditions

During the construction of the Adriatic Highway section near Rijeka, Croatia, a landslide occurred on the slope alongside a highway cut. Through lateral expansion, the landslide also affected the partly finished highway cut. Consequently, the construction works were stopped. The landslide body affected parts of the clayey slope formations formed through the weathering of the flysch rocky mass, and parts of the loosely bound layers of breccia lying on the siltstone layers in the bedrock. Complex geotechnical investigation works were carried out for the purpose of drafting a landslide remediation project. The works included core borings works, geophysical works, laboratory testing of soil and rock samples, so as geological, and geotechnical mapping works. Based on the results of investigation works, a landslide remediation design and a new highway cut construction design were made.
