Seismic Site Response Analysis And Large-Scale Shaking Table Test

The site refers to the study of near-surface in the vicinity of local geological conditions. The project site is the carrier of the seismic wave propagation, seismic wave propagation characteristics in different venues are different, and site conditions have a major impact on the propagation of seismic waves. How to estimate the impact of site conditions on ground motion characteristics is becoming an important research topic of engineering seismology. In different inclination conditions, in order to reveal the venue response law under the seismic action, especially the influence of the amplification factor of the PGA, Therefore, the mainly works we have done in this paper are as follows:1. According to research the intensity, site conditions, and surface angle, earthquake sites are systematic studied. The seismic intensity and surface inclination influence of the PGA amplification factor.2. Experimental designs, implementations and the main test results of different inclination of the venue large scale shaking table tests are firstly described in detail, variation law of amplitude and rock angle on the spectral characteristics are summarized later. And th paper researches the different inclination PGA amplification factor with a high degree of variation.3. Inorder to research PGA amplification factor and the spectral characteristics of the law of the impact under further seismic venue inclination, different seismic intensity conditions, site models based on ABAQUS finite element are established. The site is divided into three categories, hard rock, soft rock and gravel site. The model seismic effects are explored respectively in7degrees,8degrees and9degrees. At the same time, PGA amplification factor with a high degree of regularity, seismic waves and different rock formations angles is analyzed.4. Based on the achievements of this paper, the numerical simulation and the results of experiments have been analyzed. The influence factors in the earthquake field have been also analyzed. The appropriate fitting formulations have been given to discuss the effect of factors elements (constant and variables) in formulations on the PGA magnification coefficient.5. The work of this paper has been concluded, and the expected issues have been given.
