摘要
根据概率可靠性理论,计算了地震作用下地下直埋管道的各个震害等级的概率值。假定在一段管子中,其破坏为泊松公布,求得这段管道供水的可靠性,最后用并联和串联分析法,得出整个供水管网的供水可靠性。通过实际计算,结果较理想。
According to reliability theory of probability ,the probability value of different grade of seismic hazard of water pipe buried underground under earthquake action was calculated. Suppose the damage of a section of pipe is in poisson distribution,the reliability of the pipe for water supply can be obtained . Finally, the reliability of the whole pipe network for water supply can be obtained through parallal and series connection analysis method ,and the result is ideal.
