【摘要】 埋地管道是城市生命线工程的重要组成部分,在地震时较易发生震害。影响埋地管道在地震中破坏特点的因素,主要是强烈的地面运动或场地失效以及管材、管径等因素。研究方法以基于经验统计的方法在实际应用中比较多。本文分别对基于理论计算和经验统计的震害预测方法进行了简述和比较,最后提出了基于综合概率的埋地管道分析预测模型。更多还原

【Abstract】 Theearthquake damage prediction of pipeline has heavy proportion in the earthquake damage predictionof lifeline system, and the pipeline is the brittle unit of lifeline when earthquake occurs. The earthquake damage towater supply pipelineis affected by the seismicmotion and the site liquefaction, materialand diameter of the pipesetc. The methods of earthquake damage prediction of pipeline which based on experience statisticsare more practicality. In this paper the methods which based on theories account and experience statisticsare introduced and compared respectively, and a new prediction model for pipeline according to comprehensive probabilityis put forward finally.更多还原
