Abstract


The earthquake is the sudden a common geological phenomenon, the earthquake-induced ground motion is the direct cause of building damage. In particular, is the the Panxi area of ??distribution of a number of major fault zone, fault zone activities, frequent and intense seismic activity, coupled with widely distributed in this region Xigeda significantly different from the other physical and mechanical characteristics of the Quaternary research Panxi Xigeda venues dynamic response characteristics of great practical significance. Mountain building is often placed in the base platform different elevations, research venues seismic amplification due for inspection platform elevation, slope, put the slope of the cut-and-fill side constraint acceleration amplification effect. In this paper, the physical and mechanical properties of Xigeda strata as the background, solid medium stress wave propagation theory based, by means of the MTS shaking table test and finite element numerical simulation, dynamic characteristics of the Xichang Xigeda strata venue specific work in the following areas: (1) solid medium stress wave propagation theory analysis of the characteristics and constraints of the spatial distribution of ground acceleration response mechanism. The analyzed seismic wave propagation at the interface of two media reflected superimposed, resulting in surface ground motion amplification. Two media Poisson's ratio, the greater the difference, the more significant amplification effect. Specific performance medium particle displacement medium internal particle displacement is twice as large as in: when the incident P and SV waves, the energy conversion only with the angle of incidence and site geotechnical Poisson ratio about normal incidence caused by free interface; while incident SH wave, regardless of how the incident angle, caused by the surface ground motion are twice that of the incident wave. (2) the use of the MTS shaking table model test on different grading structure, different spectral characteristics and 0.25 g and 0.5 g two input level intensity earthquake differences in response to simulated; finite element numerical analysis software to study the Xigeda foundation The dynamic response behavior of the constraint mechanism. The results show that: for determining the height difference of the two platforms, the more the number of grading, may lower the level of the top platform of the acceleration amplification; greater the intensity of the input ground motion, the greater the surface peak acceleration, but the smaller the amplification factor; same input ground motion, the platform height difference the greater the surface ground motion response is more intense, and the fill area vibration response generally greater than the area of ??excavation. Therefore, the slope of the multi-level platform venue should maximize the use of the grading structure in the form of sub-station, try to avoid using upright retaining wall, and should follow the principle of \
