The mudstone is soft while the sandstone is hard and contains many opening or closing joints with a high dip angle. Some are nearly parallel and the others are nearly decussated with the trend of the slopes. Many natural slopes are in deformation or sliding because of those reasons. The stability of cutting slopes and supporting method to be taken for their stability in civil engineering are important. In this paper, the stability and deformation of the slopes are studied. The methods of analysis and support design principle are analyzed also. Finally, the method put forward is applied to study Fengdian high cutting slope in Sichuan section of the express way from Chengdu to Shanghai. The results indicate that the method is effective.展开更多

Simulation results show that the azimuthal resistivity is determined by fracture dipping as well as dipping direction, while the amplitude differences between deep and shallow laterolog resistivities are mainly controlled by the former. A linear relationship exists between the corrected apparent conductivities and fracture aperture. With the same fracture aperture, the deep and shallow laterolog resistivities present small values with negative separations for low-angle fractures, while azimuthal resistivities have large variations with positive separations for high-angle fractures that intersect the borehole. For dipping fractures, the variation of the azimuthal resistivity becomes larger when the fracture aperture increases. In addition, for high-angle fractures far from the borehole, a negative separation between the deep and shallow resistivities exists when fracture aperture is large as well as high resistivity contrast exists between bedrock and fracture fluid. The decreasing amplitude of dual laterolog resistivity can indicate the aperture of low-angle fractures, and the variation of the deep azimuthal resistivity can give information of the aperture of high-angle fractures and their position relative to the borehole.展开更多

The produced nanocomposite powders and bulks were characterized using X-ray diffraction （XRD）, transmission electron microscopy （TEM） and scanning electron microscopy （SEM） with an energy dispersive X-ray spectrum （EDS）. The as-fabricated nanocomposite bulks were added successfully into the hot-dip galvanizing bath to improve the corrosion resistance of coatings. The results show that after milling for 120min, nano-sized CeO2 particles are distributed homogeneously on the surface of fine Zn particles to form spherical-like nanocomposite powder with narrow grain size distribution. The subsequent sintering does not lead to a dramatic grain growth, and the distribution of CeO2 nanoparticles in the composite bulk is also homogeneous. With the addition of as-prepared bulks, the corrosion resistance of the galvanized coatings is improved obviously. It provides a feasible route for adding CeO2 nanoparticles into the hot-dip galvanized coating.展开更多
