Stability analysis of rock slopes and mitigation of landslide risk in the area of "Arvanitia walkaway" of the Municipality of Nafplion
Summary:
The topic of this thesis is the study of the stability of rock slopes, at the Acronauplia peninsula, where occasionally rockfalls occur. In this area and specifically along the area of study slope there is the Arvanitia path, which is visited by a large number of walkers. Therefore, it is important to determine the slope failure mechanisms to be able to suggest slope protection measures to mitigate the rockfall hazard. A specific methodology was followed to achieve the reasearch objectives. In the early stage of the study, the geological background of the area and its morphology were analysed based on field observations and with the help of bibliographical material such as maps and previous studies. The slope was separated into smaller sections in order to obtain more detailed results. At first, a kinematic analysis was carried out, by using discontinuity orientation data that were taken during the applied research of Lekkas et al (2022) in the study area, providing a first evaluation of the possible failure mechanisms that can occur along the slope. Then, stability analyses were carried out and the Safety Factors were estimated for each section of the slope. In those cases where the Safety Factors did not take acceptable values, simulations of protection measures and therefore measures that improve these values were carried out. The analyses showed the necessity of anchoring the potentially unsafe rock masses in several parts of the slope. Then, rockfall analyses were carried out with the RocFall software at six sections of the slope with unfavourable topography. During this process, a number of simulations were carried out for each section and values of the expected kinetic energy of the rock masses and their final location after the completion of the path were obtained. From this data, the appropriate locations for the placement of measures to manage these rockfalls were estimated.
