On the basis of the concept and analysis method of slope geological structure, four typical slope geological structures are selected by some investigations on more than one hundred high rock slopes in the motorway project. these structures are thick sandstone stratum, stratum including weak coal, stratum made of red or brown plastic clay and soft rock mass and stratum made of remnants rock mass. the practical slope geological structures are compact basis of geological mechanical model for the analysis of relaxation zone in high rock slope projects

Based on the analysis of thin sections by microscope, measurement of porosity and density, and geological setting, we tested the rock physical parameters of sandstone, siltstone, carbonate and other transitional sedimentary rocks by the mts system under formation conditions ( temperatures, pressures and pore fluid properties ). the rocks we tested are from tertiary ( including zhujiang formation, zhuhai formation, enping formation, hanjiang formation ) of zhujiangkou basin in southern china sea. according to the analysis results, we studied the main ultrasonic wave velocity characters of rocks, which are compressive and shear wave velocity and poisson ' s ratio under different formation conditions
