  2. Stability of rock slopes is generally controlled by the structure of rock masses, especially the soft structure surfaces. analysis of rock mass structures is a key to establish geological models and numerical simulation and a foundation to assess the stability of rock slopes. the weak structure surfaces are mainly bedding planes, faults, joints, schistosity plane and contact zones of intrusive bodies. since they are different in genesis and scale, the rock masses are different in features and mechanical intensities. based on the combination of rock structure bodies, 15 basic modes of deformation and failure of rock slope are systematically summarized. the deformation and failure of rock masses actually result from the recombination and rearrangement of these rock bodies. there are 11 types of rock mass structures and various deformation and failure of bank slopes are present in the reservoir area of the three gorge project

  3. Previous researchers have always determined the sp atial distribution patterns ( sdp ) of castanopsis kawakamii with a sample - dis tance method. however, the distribution patterns may be affected by the quadrat si ze and, in the course of analysis, the density differences among the cluster plots are not considered ; therefore, differences of cluster plot size and the dispersi on degree among individuals of cluster plots can not be known. authers of this pa per have determined the spatial distribution patterns of castanopsis kawakamii population in different habitats by means of non - quadrat distance method and a nalysed the pattern intensity and grain of the sdp. the pattern intensity is defi ned with the relative density differences and the pattern grain can embody the d ispersion degree of the individuals in the plots, and the dispersion degree among the plots. the determined results are as follows. the intensities of the species range in order from strong to week : litsea mollifolia p. kawakamii i. purpure a r. cochinchinensis c. kawakamii c. carlessii d. oldphamii s. superba. the gra ins of the species queue in order from coarse to close : s. superba = litsea mollif olia r. cohinchinensis c. kawakamii = i. purpurea c. carlessii p. racemosam d. oldp hamii. these determined results tally basiclly with the results authers of this paper have got in determining the same plots by means of aggregate index access ing method. in view of this, it is held that the sdp of c. kawakamii is closely related to the habitats and biological features
