| Abstract: | In this paper based on the analysis of conditions of regional geology, the engineering properties of rock masses, mainly, its behavior of deformation under differential loadiog conditions have been studied. After a comprehensive examlnation of theinfluence of engineering acting forces and the environment factors on deformation character of rock masses the principle of the selection of the abutment type and the significance of using combined abutmeut on improring the stress situation of rock messes and restricting the unfavourable factors is discussed |
