Abstract
According to influence degree of earthquake action on the buried pipelines, applying the method of numerical calculation to obtain analytic solutions of vibration mode function. Stationary random vibrations of buried pipeline in the calculation method of hypothesis is linear vibration problem, has zero mean and response pipe soil system incentive, co-variance function and correlation function to get is the same. According to the analytic solution for buried pipeline stationary vibrationsolution, lateral vibration analysis of pipeline. The results show that:the horizontal vibration of the pipeline, the central stress and displacement tends to a constant, the boundary region of the stress and displacement change, the lateral ride vibration of buried pipeline in the maximum stress occurs in the slip boundary.关键词
