Abstract
本文对地震波在均匀边坡内的传播规律进行了初步探讨。从地震波能量传播的角度，对边坡的整体稳定性进行全面，细致地分析。在实际工程中如果对整个边坡进行分析，计算量过于庞大。因此，本文通过地震波理论将边坡内部分成若干个影响区域，推导出每个区域的位移函数，可以有效降低理论分析的难度。通过位移矢量时程分析，得出边坡危险区域和潜在的滑动面。采用位移矢量分析得到的结果和实验结果较为吻合。 This study discusses the propagation law of seismic wave propagating in the isotropic rock slope. In view of energy distribution, we can investigate the stability of slope carefully and comprehensively. But the computational cost is very high for analyzing the dynamic response of all the points of the whole slope based on the seismic wave theory. In order to reduce the difficulty, the rock slope can be divided into different region according to the propagation law of seismic wave; the displacement functions only for different regions are needed to be evaluated. The dangerous region and the potential sliding surface could be determined by the time-history analysis of displacement vector. The displacement response obtained by time-history analysis is consistent with the results observed from the experiment.
