校园地下管线抗震评估初步探讨
|
摘要
对前人有关直埋地下管线的震害及其影响因素进行了简单总结,整理分析了前人关于管线震害评估的有关标准。结合某学院实际管网的资料,进行了各种管线的震害率计算,并对其进行了基于郭恩栋方法的震害等级评定及影响因素分析,得出:(1)设防烈度下管网系统在应急上能基本满足要求,但在使用功能上需进行修复;(2)对于断层影响,管道与断层应呈60°交角并采取抗震构造措施;(3)管网设计中应选用韧性、大口径、大曲率弯头的管材。
This paper summarizes the buried pipeline damage and influence factors in earthquake,collects and sorts out the relevant standards about pipelines seismic damage assessment;Combining with the data on actual pipeline network of a college,various seismic damage rates of pipeline were calculated and Guo Endong's method-based seismic damage gradation assessment and relative influence factors analysis were carried out.It is shown that:(1)under seismic fortification intensity the pipeline system can basically meet the emergency requirements,but requires a rehair in usage function;(2)for the fault effect,pipeline should hold a 60° angle with fault and accept correspoding seismic construction measures;(3)the pipe network design should use tubular product with toughness,large-diameter and high curvature elbow
