| 摘 要： | 用弹性基础梁理论导出水平L形弯管在地震时的内力计算公式,并结合我国地震地区的实际情况,运用本文公式对震区管道强度进行了核算。结果表明,铺设在地震烈度9度地区的埋地管道不会发生损坏,若管道铺设区的地震烈度达到11度时,埋地管道将发生损坏。这与本文的理论分析基本符合。

| Abstract: | An equation for calculating the internal forces in a horizontal L-shaped pipe during earthquake was derived on the basis of the theory of elastic beam.The equation was used to calculate the strength of pipeline buried in the earthquake area in China.A pipeline buried in the earthquake zone with an earthquake intensity of nine-grade did not break but did break in the zone with eleven-grade intensity.The result agrees with the theoretical calculation. |
