台安盘锦输水管道震害分析

ANALYSIS OF EARTHQUAKE DAMAGE ABOUT WATER PIPELINE

强烈地震波的传播及砂土液化是造成地下管线发生破坏的两类原因。对台安－盘锦输水管道采用模拟弹性地基梁轴向运动形式来进行抗震验算，并采用模糊数学理论及泊松分布函数来进行破坏概率的计算。综合分析出输水管道的破坏等级和破坏概率。

The propagation of violent earthquake wave and sand liquefaction are two reasons to make underground pipeline damage。We have examined the pipeline antiseismicfaction by simulating axial section of the elastic foundation beam,and calculated damage probability by using vague mathematics theory and boisson distributed function。The damage degree and damage probability of the water pipeline have been worked out。
