Interest in rock slope stability in mountainous regions has increased greatly in recent *** issue has become a topic of major interest for geoscientists and engineering professionals,as well as for private citizens and local administrators,in many parts of the *** paper evaluates the stability of seven rock slopes along the KamyaranMarivan tourist road,Kurdistan province,Iran,using various *** two main reasons for performing this research were to determine whether different methods of stability analysis provide the same results,and to determine how different factors such as the presence of water,tension cracks,and seismic forces affect the stability of these rock ***,field investigations were performed to obtain the engineering characteristics of the rock masses,discontinuities,and intact rocks of the ***,laboratory tests were carried out on rock samples obtained from the slopes,to determine the engineering properties of the intact *** for each rock slope,the contour diagram of discontinuities and slope face was drawn in the Dips v.5.1 software environment,and the failure mechanism was determined based on the kinematic or stereographic ***,the factors of safety of the rock slopes were calculated using the limit equilibrium method,based on the failure mechanisms resulting from the kinematic *** accuracy of the results obtained by these two methods was investigated using SWedge v.4.0 *** results indicated that four rock slopes have a potential for plane,wedge,and toppling failure,and three others are ***,it was found that the stability of the studied rock slopes decreases greatly in the presence of water,tension cracks,and seismic forces.

As it is commonly known,the estimation of physical and mechanical characteristics of rocks is very important issue in various geotechnical *** characteristics are mainly influenced by the microfabric-texture features of *** this research,dry unit weight,effective porosity,point load index,Schmidt rebound hardness,uniaxial compressive strength,and texture coefficient were measured with the aim of correlating the physical and mechanical properties to the texture *** this purpose,a comprehensive laboratory testing program was conducted after collecting twenty sedimentary block samples including nine limestones and eleven mudstones,taken from Kalidromo(central Greece)in accordance with ASTM and ISRM ***,mineralogical and petrographic properties,textural characteristics as well as X-ray diffractions were studied and the obtained results were statistically described and *** maximum and minimum values of the texture coefficient were 0.13 and 0.50,*** highest value was obtained for the rocks with a large amount of *** analyses were used to investigate the relationships between the texture coefficient and the engineering ***,empirical equations were developed and because of the good determination coefficients,they showed that all of the engineering properties were well correlated to the texture coefficient.
