Fig.1 Finite element model of slope For the reservoir bank’s slope, soil’s yield strength is mainly produced due to the shear factors ，thus the Mohr-Column criterion is most suitable for the slope stability question’s calculation.
The shear strength parameters of the land’s sliding surface based on the laboratory test and combining the local experience value to get the comprehensive value(the soil test standard value), the shear strength parameters of the underwater part’s sliding surface should use the effective stress intensity index, if the site does not have test conditions, effective stress strength indexes should be determine according to combine the experience value and near the site’s slow shear test value,showing the parameters in Table 1, showing soil mechanical properties parameters in Table 2.

The structural parameters of HEMs are the main factors which determine their vibration isolation characteristics.
Flower [3] explained the operation of inertia track and decoupler using a bond graphs mechanical method of the hydraulic mount.
Experimental data were used to show the effectiveness of the mount, and Flower showed that the hydraulic mount could meet two conflicting design criteria by exhibiting nonlinear dynamic properties.
Then the spectra of the test time-domain signals were analyzed and the dynamic properties, i.e., dynamic stiffness K* (complex spring rate), dynamic stiffness modulus K, dynamic stiffness in-phase (dynamic spring rate) k, loss angle φ (or loss tangent tan φ), dynamic stiffness out-of-phase (loss rate) k΄ and equivalent damping coefficient b were obtained:

This approach involves the consideration of heat, air and moisture (HAM) transfer and control of a building, specifically, how the coupled relations between different transient systems (mechanical system, building envelope, indoor environment, outdoor environment, and occupants) affect the building performance and operation.
Future tests will be undertaken to consider other factors such as indoor air quality based on carbon dioxide concentration, heating and ventilation energy consumption, and alternative finishing materials.

Based on existing knowledge on the moisture buffering of materials, it may be possible to create a suitable indoor environment by using alternative finishing materials that may have different material properties than conventional drywall, which may maximize the moisture buffering ability.
