This calculation method does not fully consider the overall structure of work performance, and the impact of damping ratio of composite structure formed of different materials, Literatures[2-3] shows that: lattice shell's support conditions on the dynamic characteristics and seismic response have a major impact, therefore, reasonably calculate the seismic response of lattice shell structures must be considered the impact of the overall structure's work together and damping ratio of composite structure formed of different materials.
Lattice shell material parameters are as follows: The lattice shell's bar use Q235 steel, modulus of elasticity E=2.06×105Mpa, mass density ρ=7850kg/m3, poisson ratio 0.3; Independent column use C35 concrete, modulus of elasticity E=2.55×105Mpa, mass density ρ=2500kg/m3, poisson ratio 0.2.
(3)Damping ratio of the whole structure can not take 0.03 by experience, damping ratio calculation for this combination of different materials should be adopt test value of scale model or calculated value by equivalent structure theory method

Based on observations of engineering practice and reference materials, the shallow drainage method ensures cutting slope stability in technical solutions, and then related tests are carried out.
The geotextile filter materials are used in shallow slope drainage, and Geocell with deep-rooted plants iris grass is used as slope protection engineering measures.
